The changes to the code did not search our custom fields. I added this line:
$cust_array = $aCustom_item . '_str';
at line #352 of advanced-search-by-my-solr-server.inc.php
Adding this line returns results that match items in custom fields. I wish I was more familiar with the plugin and SOLR to know why this change matters, but it does in our instance.
On another note, I have a request:
We currently have a TON of custom fields in our system. If we select them all we get a timeout and the search doesn't work because it's sending the request by get and the request is too long. Would it be possible to add an option to search all custom fields without having to check each checkbox, which then sends a request that is too big?
thanks for working on this,
