Xapian discuss - Jan 2006 - Bindings Vs Omega multi bool

Evening All,

Having fun and games with the PHP bindings.

If I run the following through omega I get 51 hits:

/usr/local/lib/omega/bin/omega P= DB=boris FMT=xml 'B=XL3'
'B=XRANGE3'
'B=XRANGE4' 'B=XRANGE5' 'B=XSOLD0' 'B=XUNDER0'

If I have the following php code:

$query = new_query ("XL3");
$query = new_Query_from_query_pair(Query_OP_FILTER, $query,
new_Query("XSOLD0"));
$query = new_Query_from_query_pair(Query_OP_FILTER, $query,
new_Query("XUNDER0"));
$query = new_Query_from_query_pair(Query_OP_FILTER, $query,
new_Query("XRANGE3"));
$query = new_Query_from_query_pair(Query_OP_FILTER, $query,
new_Query("XRANGE4"));
$query = new_Query_from_query_pair(Query_OP_FILTER, $query,
new_Query("XRANGE5"));

I get Zero hits.

The output of Query_get_description prints the following:

Xapian::Query((((((XL3 FILTER XSOLD0) FILTER XUNDER0) FILTER XRANGE3) FILTER
XRANGE4) FILTER XRANGE5))

If I have the following PHP code:

$query = new_query ("XL3");
$query = new_Query_from_query_pair(Query_OP_FILTER, $query,
new_Query("XSOLD0"));
$query = new_Query_from_query_pair(Query_OP_FILTER, $query,
new_Query("XUNDER0"));
$query = new_Query_from_query_pair(Query_OP_FILTER, $query,
new_Query("XRANGE4"));

I get 19 matches with the Query_get_description printing the following:

Xapian::Query((((XL3 FILTER XSOLD0) FILTER XUNDER0) FILTER XRANGE4))

I get 19 matches from omgea for the following:

/usr/local/lib/omega/bin/omega P= DB=boris FMT=xml 'B=XL3'
'B=XRANGE4'
'B=XSOLD0' 'B=XUNDER0'

Why is the multiple XRANGEs working in omega and not through the bindings, what
am I doing wrong.

Any pointers whould be helpfull...its been a long Sunday!

Cheers
John

Omega will OR boolean filters with the same prefix.  So it does:

query FILTER (XRANGE3 OR XRANGE4 OR XRANGE5)

Sorry if its a basic question but I am just getting my head into the PHP
bindings after using omega for months.

How do I get the bindings to OR the XRANGE?

Cheers
John

$q = new_Query_from_query_pair(Query_OP_OR, new_Query("XRANGE3"),
new_Query("XRANGE4"));
$q = new_Query_from_query_pair(Query_OP_OR, $q, new_Query("XRANGE5"));

0.9.3 will allow you to build a query using an operator and an array,
which would be useful for this sort of case.
