Product filter - FilterVier_SEO OCFilter - Product filter module How is this module different from other search modules? Common search modules include: standard OpenCart search search , other search modules, such as the "Search with morphology and relevance" module. How do they work? After the user has entered a search phrase and clicked the "Search" button, the search module, in order to find all the products that match the search phrase, must look into all the products in the database, and information about each product is not in one, but in several tables with many fields, many of which are not indexed in any way. If you have a few products on the site (tens, hundreds) and a fast server, then your search will work quite quickly. But if you have thousands of products in the store (or even tens and hundreds of thousands) or not the fastest server, then the more products you have, the slower the search on your site will work. In some cases, 5 and 10 or even more seconds, which of course is a lot, everything that is more than 1-2 seconds is already a lot, users will not wait that long, they will close your site and go to another one. How does this module work? This module works on the same principle as search engines, which is why it is called so. Let's take the Google search engine as an example. After you enter in the search field, for example, " OpenCart " into the search box and click the "Search" button, Google will show you the results you need in a fraction of a second. This is possible because Google does not search for information directly on each site at the time of the search, it has already bypassed all sites and added this information to its very fast databases, where all entries are indexed and lie in the database with the necessary weights (which site to show higher in the search results, which one is lower). After that, Google searches its databases, this makes it possible to find hundreds of thousands of sites in a split second! This is exactly how this module works. First, it opens all the products in the store and adds all the information to its own database tables with indexes. When a user searches for something on the site, the search does not bypass dozens of fields in thousands of products, but searches only in one table for one indexed field, so the user will receive the result not in a few seconds or even tens of seconds, but in a fraction of a second, which is tens and even hundreds of times faster than a standard search. Morphology and relevance As you know, the standard OpenCart search is just awful. When searching, it breaks the search phrase into separate words, after which it finds all products that contain any of these words. As a result, when searching for the phrase " Samsung Monitor " in the first positions may be " Acer monitor " (because the name contains the word " monitor ") or " Samsung laptop " because the name contains the word " Samsung ". While the right product " Samsung Monitor " may be somewhere on the 10th page. And if you write in the search not " laptop ", but for example. " laptops "" then the search will not find anything at all, since the search is carried out only by the exact occurrence of the word. This module is written to fix all the shortcomings of the standard search. To do this, he has 2 tools: Morphology. Search is not by exact match, but by the roots of words. Now, by writing "laptops" in the search, the search will return all products in which there are "laptops" and "laptop" and "laptop", etc. Supported dictionaries - Russian, Ukrainian, English. Relevance. When searching, the first positions will be products with a large total weight. The highest weight has the exact occurrence of the phrase at the beginning of the product name, then the occurrence of one or more words in the name (the more words, the greater the weight), then the occurrence of the word in the tag, then the whole phrase in the description, then a single word in the description. The more matches, the more weight and the higher this product will be in the search results. The weight of each match can be adjusted in the admin panel. What's new in the 3 version of the module? Search Added search using transliteration For a long time, many have asked to implement this, I did it. Added the ability to specify the search order between searching with the wrong layout, transliteration, inaccurate search Previously, it was hard coded in the code, first there was an inaccurate search, and then if the inaccurate search did not find anything, then the search was already performed by the wrong layout, which was not always convenient. Added fine-tuning search by Category. Products from certain categories can be displayed higher or lower in the search, or removed from the search. Example. There is a store that sells mobile phones. Along with phones, he also sells accessories for them: cases, protective glasses, headphones, etc. In the name and description of accessories, there is often a phone model, which is also often repeated, since models can differ by 1 letter. And when a user searches for a phone by model, the user himself wants to see phones in the search, and it is much more profitable for the store to sell the phone, but in the search, covers or protective glasses can be in the first positions, and the phone of this model is far lower in search results. The new function solves this problem, now you can configure the search much more flexibly. Added fine-tuning of search by Manufacturers. Products of certain manufacturers can be displayed higher or lower in the search or removed from the search. The same as for categories, only for manufacturers. A store can, for example, raise the manufacturer's products in the search results, for which the store has a higher margin and more profit from their sale. Added setting by parts of speech. For certain fields, you can increase or decrease the weight of words of a certain part of speech, or not add them to the index at all. For example, you can not add to the index such parts of speech as prepositions, conjunctions, interjections, etc. And the weight of nouns or verbs, on the contrary, increase. Works only for the Russian language. Added the ability to search by exact match of a word, in earlier versions there was a search only by the roots of words. Since the search used to search in parts of words, sometimes the exact match of words was lower in the search results than words with incomplete matches. For example, a user could search for "red dress" and the product "Red belt for a dress" could be in the first position, and the product "Red dress with white polka dots" could be lower in the search results, despite the fact that all 2 words in it exactly match. This feature fixes that. Added an option to not display products that are out of stock in the results, in earlier versions it was only possible to display them at the end of the list. Also, many have long asked to implement this, done. Added synonyms. Now you can register sets of synonyms and the product will be located both by the main word and by its synonyms. For example, using the word "phone" to find products where there is a "smartphone". More than a dozen other improvements in search, indexing, design, and more. All of them are not very big, but together they also significantly improve the whole search. What's new in the second version of the module? Search by occurrence of a word and by suffixes. This was very lacking in version 1, since many needed a search by entry for, for example. model or article. But this was not in version 1, because such a search, if done simply, would greatly (hundreds of times) affect the speed of the search. In the second version, the functionality of a quick (!) search by occurrence was written. More accurate relevance. In version 1, there were 2 weights for a word: if the word is the first (in the product name, for example) and all other words. That is, the word of which the second and the word of which the 20th had the same weight. Version 2 has 2 weights: the weight of the first word and the weight of the last word. All other words inside get weights dynamically depending on their position and the number of words in the title. Thus, the closer the word is to the beginning, the more weight it has and the products that have the search word closer to the beginning will be displayed higher in the results. Moreover, if the search goes by occurrence, then the weight is also cut in proportion to the part of the word. This achieves a greater accuracy of search relevance. Added inaccurate search, search for words consonant with the desired. That is, you can find goods, even if you enter a word with a typo or a grammatical error, of course, not all errors will be found by the module, but many - yes. The best search algorithm using AND logic. This part of the code has been completely rewritten, now in the module such a search works according to a new algorithm that does not affect the speed and more accurately finds only products that contain all the words from the search phrase. Opencart 3.0 support Capabilities the module is written on the basis of the "Search with morphology and relevance" module, therefore it contains all the huge functionality of that module using morphology and relevance for more precise search selection of search logic for searching by phrases of several words: AND, OR multi store support the ability to disable the date of receipt of goods in the search different types of search (by exact match or by the beginning of a word) keyboard layout fix mode ("фззду" -> "apple") consider stock availability (out of stock items will be displayed at the end of the search) option to enable results caching the ability to add new search fields, for example, you can add a search by product id, H1 meta, and almost any product field. for each field, you can: enable morphology, specify the minimum word length, specify the weight of the occurrence of a word in the beginning or middle of the field the ability to exclude certain words from the search the ability to replace words when searching (for example, misspelled words: "aple" -> "apple") support for several indexing modes: indexing by krone, automatic indexing after each addition, change, deletion of a product, manual indexing on the module settings page with support for batch creation of indexes (you can start the process and leave the page open for a long time) search by entry inaccurate search What's new in the 2 version of the module?

Opencart 3.0 support Module version comparison table Search with morphology and relevance version 3 Search Suggestions- Search with autocomplete, version 5 This module is Search system, version 4 Search speed low low very high Relevance average no very high Logic AND average average very high Search by entry yes (slow) yes (slow) yes Inaccurate search no no yes Transliteration no very high yes Change layout no very high yes Category coefficients no no yes Coefficients for manufacturers no no yes Parts of speech settings no no yes Search by exact word match no no yes Synonyms no no yes Header Search no* yes no* Opencart support 1.5 - 3 1.5, 2.0 - 3 1.5 - 3 * - in the module Search engine and Search with morphology and relevance there is no header search, because this functionality is implemented by a separate module - Search Suggestion. This is done for more flexibility. These modules work great together (if you have the Search Engine module, the Search Suggestion module searches for products through the Search Engine module) but can also work separately. It is better, of course, to use them together. Compatibility: OpenCart / ocStore 3.x, 2.0.x, 2.1.x, 1.5 The module uses IonCube, usually 99% of hosts use it, but just in case, you can check . One module license allows you to install this module on 1 domain.
