John……YOU ARE THE MAN! Thanks to your custom field search article (the one you mentioned in this article), I was on the hunt for Sphinx….sadly it doesn’t search and index custom fields….however, THIS POST seems to have that solution for me, as Ivinko want’s $300 to modify their plugin to function with custom fields.

My question to you is…..Should I just copy the changed files and store them for when they have a Sphinx update, or should I just not update when their updates come around?

Using a serialized array does get tricky. You have to unpack part of the array in the SQL statement and only use SQL to do it. Say you are given meta_value along the lines of: custom.meta_value = "aaa,bbb,ccc"
You can unpack that and assign each piece to an sql column:

SUBSTRING_INDEX(SUBSTRING_INDEX(custom.meta_value, ",", 1), ",", -1) as first,
SUBSTRING_INDEX(SUBSTRING_INDEX(custom.meta_value, ",", 2), ",", -1) as second,
SUBSTRING_INDEX(SUBSTRING_INDEX(custom.meta_value, ",", 3), ",", -1) as third,

You might also need to use TRIM to remove any quote marks. Hope that points you in the right direction.

Hi, thanks for this!
i have a serialized Array in one meta_value. Is there a way to make them searchable too?

My post concerned how to modify an existing plugin, Sphinx Search, to perform searches on custom fields. I have not created a plugin to handle custom fields automatically. The primary reason for this is that using custom fields heavily in a Wordpress installation already requires a lot of customization--so adding another plugin into the mix isn't really necessary.

Hey John, this was really helpful! I don’t think there’s another site which explains how to do it.

Thank you very much,

Andres.
