[Xapian-discuss] Multiple filters with PHP? How to?

[athlon athlonf]

Yes there are documents matching both boolean terms:

Using filter G68 gives me 219 results


			
Parsed query is: Xapian::Query((Zandi:(pos=1) FILTER G68))


Using filter XAUTHORID5 gives me 19 results



			
Parsed query is: Xapian::Query((Zandi:(pos=1) FILTER XAUTHORID5))

But on a different subject:
If I want to filter at datetime and string, how should I do that?

 author = "the author" 
$qarray[] = new XapianQuery('Athe author');
Won't give anything

As well: startdate = ">01-01-2008"

Do you have documents that match both those boolean terms? Try just
searching for the terms directly without the rest of the query.

That looks believable, yes - I just can't remember which options PHP
supports :-)
