If you have made several changes to already indexed products, you might prefer to choose to re-build the whole index. The "Re-build entire index" process takes more time, but it is more thorough.
PrestaShop also gives you the URL to let you create a cron task for regular re-building of the index. If you do not know about cron and crontab, ask your web host about it.
Finally, the "Indexation" option enables you to have a product be indexed as soon as it is created/modified, thus rending the above links and cron link useless.
Search options
This section enables you to configure the behavior of your shop's search function:
- AJAX Ajax search. Enabling it displays a list of 10 results from the moment your customers type a few letters into the search bar, right under the search bar.
- Instant Searchsearch. Enabling it displays a list of results from the moment your customers type a few letters into the search bar, directly within your shop's main content area. This setting is disabled by default, because visitors are not always used to have their whole content changed just be entering a few letters in the shop's search bar. Therefore, use with caution.
- Minimum word length. You can choose the minimum size at which a word may be registered in the search index and found by your customers. This feature allows you to eliminate short words in the search, such as prepositions or articles (the, and, of, etc.).
- Blacklisted words. You can choose the terms that must not be found by your visitors. Enter them directly into the field, separated by "|".

As indicated in the section, the search "weight" of a product represents its importance and relevance for the ranking of the products when customers try a new search.
An item with a weight of 8 will have 4 times more value than an item with a weight of 2.
