String filter in PHP client does not work

[GoogleCodeExporter]

What steps will reproduce the problem?
1. In Sphinx 1.10-beta conf create a source and add a sql_field_string = field
2. In PHP Client API (version from 2010-06-29 14:08:19) try to use 
$cl->SetFilter('field', array('value'));
3. Get Assertion Failed errors

What is the expected output? What do you see instead?

I was expecting to see the result set, instead I see no results (and the 
Assertions errors)

What version of the product are you using? On what operating system?

1.10-beta on Linux 32bit with PHP API version from 2010-06-29 14:08:19

Please provide any additional information below.

As far as I understood Sphinx 1.10-beta "added string attributes support 
(sql_attr_string, sql_field_string, xml_attr_string, xml_field_string 
directives)" however the PHP API cannot use string filters.

I also try using the lastest PHP API from trunk (today 24th Feb 2011) without 
success.

Ops,

it seems that this is not as I understood, I just read the following in the 
manual and would like to recall the issue I opened.

"As of 1.10-beta, strings can only be used for storage and retrieval. They can 
not participate in expressions, be used for filtering, sorting, or grouping 
(ie. in WHERE, ORDER or GROUP clauses)."

Cheers
