Does OP_NEAR works with stemming?
Hi All,
I used the OP_NEAR operator for queryparser, and when I searched for "apple store" from my own collection, the query is parsed as "Zappl:(pos=1) NEAR 11 Zstore:(pos=2)" but retrieved nothing. However, if I type in "Apple Store", the query is parsed as Xapian::Query((apple:(pos=1) NEAR 11 store:(pos=2))) and some results are showed. I'm not sure whether

Slow phrase performance
...esn't seem
to help on common terms. I am not limiting the number of matches -- I
want all of them. But even on small sets like "kansas state" with
just 334 results, it's taking a long time.
The following are set:
$qp->set_default_op(OP_AND);
$qp->set_stemming_strategy(STEM_NONE);
Flags enabled: BOOLEAN,BOOLEAN_ANY_CASE,WILDCARD,PHRASE
------------------------------
I have been unable to find reports of other people experiencing the
same problem with poor phrase performance, so I am hoping it's simply
something that I'm doing wrong or ineffectively. Any help wo...

QueryParser prefixing terms when stemming?
...nglish'));
$qp->set_default_op(OP_AND);
$qp->set_stemming_strategy(STEM_SOME);
warn $qp->parse_query($search_term);
In version 1.0.0.0, the same code results in "Xapian::Query(Zpet:
(pos=1))". The result is no matches, even though the term pet
exists. If I use STEM_NONE, the output is the same as the output
from 0.9.9.1 and there are matches.
It seems like the Z is a prefix, but since I'm new to Xapian, I'm not
sure. Could someone guide me?
Cheers,
Tracy
