Searching by Taxonomy Terms in Ajax Search Pro
{% endembed %}

## Solution 1 - Regular engine (default)

```
Search Sources -> Post Type Search -> Search in Terms (categories, tags)
```

If you need to look for phrases in categories or other terms and return the related custom posts, then you should turn on this option.

*Please not that this option is extremely resource heavy! Sites with lots of posts/products will most likely experience higher delays in ajax search. In case of performance issues, please consider using the second solution.*

## Solution 2 - Index table engine

```
Index table (submenu) -> General options -> Index taxonomies
```

If you are using the index table engine, you can choose which taxonomy terms to index along with the post types you have choosen.

*Please note that this solution only works if you use the index table engine. You can read more* [*about using it here*](/index-table.md)*.*
