title: Is there any data query library for Javascript?
body: <p>I saw the searching > complex search demo on <a href="http://www.trirand.com/blog/jqgrid/jqgrid.html" rel="nofollow">http://www.trirand.com/blog/jqgrid/jqgrid.html</a> and really liked the advanced search box which has powerful query-based search very close to Excel. I want to reuse this advanced query interface for other applications and purposes instead of jqgrid. Is it possible to reuse it to query external json data without going through jqgrid? I don't know how jqgrid build it so I'm wondering if it is some built-in jquery UI search module or plugin that i'm not aware of. Thanks in advance if you can offer some tips. </p>
