Search Engine

Regular and Index table engine - what are the main differences?
The plugin offers two separate search engines, the regular and the index table engines.
We generally recommend using the Index Table engine for all installations, the regular engine will do just fine for regular use-cases.
Please check the 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
