## Index Table FAQ

### Do I have to re-generate the index table every time I add or edit a post?

**No**, you don't have to. Once you configured and generated the first index table, it's done automatically. You can however turn this feature off, and also enable a wp\_cron job under the *Indexing & Cron* panel.

### I want to search PODs custom field contents, is it possible with the index table?

**Yes**, by choosing the custom field under the General Options panel, the plugin will index it's contents - even fields, which are attached to a custom database table.

### The table generation is failing, what should I do?

Try to lower the `Post limit per iteration` option on the `Index table` submenu, under the `Advanced Options` panel. Try 10 first, and go lower if that doesn't work either.

### Should I use the index table engine?

Short answer, yes, you should. You definitely should if you:

* Want to search shortcode content
* Want to search tags, categories or any terms related to posts
* Custom fields content
* Have a big database of posts

### Which type of content can be indexed?

You can index posts, pages and any custom post type (products, forums, topics, etc..) as well as [attachments](https://documentation.ajaxsearchpro.com/general-settings/search-in-attachment-contents-pdf-word-excel-etc..).
