What does this module do?

Search module. Designed for stores that need high-quality and fast search. That is, for almost all stores, because with a bad search, stores constantly lose tens of percent of their profits! Your customers won't have to manually browse through tens of thousands of pages on your site to find the right product. If the product is not found in the first seconds through the search, then the user simply leaves your site.

The module was tested on a store with more than a million products!

How is this module different from other search modules?

Common search modules include: standard  OpenCart 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:

1. 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.
2. 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.

Who needs this module?

• sites that have a lot of products, to increase the quality and speed of search.
• anyone who wants to have a very fast and high-quality search on their site.

Just go to your site's search page, enter a search phrase (3-5 words, or more) and click "Search". If you get the search result in more than 1-2 seconds, then you most likely need this module.
