Search faster. When your Wordpress search fails, when your WooCommerce search or bbPress search gets stuck, you need a change of search technology.

== Description ==

Test WPSOLR features on <a href="https://www.wpsolr.com/?s=WOOCOMMERCE+OR+ACF+OR+BBPRESS+OR+WPML+OR+POLYLANG+OR+GROUPS+OR+s2MEMBER&post_type=&camp=3">our documentation search page</a>: live suggestions, facets with acf, geolocation.

You definitely need wpsolr search if you agree with one of:

- My current search page, my instant (live) product suggestions, are so slow that my visitors are leaving without buying anything, without subscribing to anything

- I have too many posts, products, visitors, comments, and I cannot afford hundred of dollars on external search hosted services

- Most of my data is stored in pdf files, word files, excel files. I need to search these formats too.

- My customers are international, they speak different languages. My search should be multilingual also.

- I want a modern search with tons of features. Ajax, facets, partial match search, fuzzy match search.

- I want to filter my woocommerce search results with any taxonomies, custom fields, attributes, or variations.

- I have several sites, unrelated, but I want to give my visitors a single search page combining all their content

- My bbPress search cannot handle thousands, hundreds of thousands of topics and replies.


If not, there are plenty of great search plugins out there to help you.

But, if you're really ready to unleash the beast, visit <a href='https://www.wpsolr.com?camp=2'>wpsolr.com</a>, ask us any question, or just download wpsolr search to give it a try.

= What WPSOLR can do to help my search ? =
Relevanssi, Better Search, Search Everything, are really great because they do not need other external softwares or services to work.

WPSOLR, on the other hand, requires Apache Solr, the worlds's most popular search engine on the planet, to index and search your data.

If you can manage to install Solr (or to buy a hosting Solr service), WPSOLR can really help you to:

* Search in many sites for aggregated searches

* Search in thousands or millions of posts/products

* Search in attached files (pdf, word, excel....)

* Filter results with dynamic facets

* Tweak your search in many many ways with Solr solrconfig.cml and schema.xml files (language analysers, stopwords, synonyms, stemmers ...)

= Do you offer a premium version ? =
Yes. Check out our <a href="https://wpsolr.com/pricing">Premium Packs</a>.

= Can you search in several sites and show results on one site ? =
Yes, there is a (Premium) multisites option in wpsolr.

You configure the sites belonging to the network search as "local", and one or several "global" sites to show results from "local" sites consolidated, while "Local" sites continue to search their own data.

As Solr manages the whole network search, there is almost no limits to the number of "local" sites, and number of posts indexed.
Contact us for more information on this multisites feature.

= Can you manage millions of products/attributes/variations ? =
Yes (Premium for attributes/variations). WPSOLR is based on the mighty Apache Solr search engine. It can easily manage millions of posts, and fast.

You have to select the admin option "Replace standard WP search", and verify that your urls permalinks are activated.
