# Search Engine

The plugin offers two separate search engines, the **regular** and the **index table** engines.

We generally recommend using the [Index Table engine](../index-table) for all installations, the regular engine will do just fine for regular use-cases.

Please check the [Index Table](../index-table) documentation on how to configure it.

| Regular Engine                                                | Index Table Engine                                                                |
| ------------------------------------------------------------- | --------------------------------------------------------------------------------- |
| Okay for smaller databases (>1000 items)                      | For any database size, but excellent for performance for bigger ones              |
| Slower, as it uses the WordPress tables for search            | Very Fast - as it uses the custom generated database for the keyword search       |
| Can do Exact Matches on consecutive keywords                  | Exact matches are only possible per keyword                                       |
| Can **not** search shortcode contents                         | **Can extract and search** shortcode contents                                     |
| Only simple relevance calculation due to database limitations | Excellent relevance calculation - as matched keyword occurences can be calculated |
