search for: parse_query

I use the QueryParser::parse_query() method but I see it uses "OR" by default between words? Is there a way to make it use "AND" instead? I see there are flags I can pass to the parse_query() method but none seems to allow a switch from OR to AND. I would like to do that without having to write my own query p...

Hello, Thanks Olly , by following to your suggestion I could do the indexing in the CSV file while the search results retrieved from the Postgres and it's working fine. [ I am using the Xapian PHP-binding to index and search.] How could I enable the WILDCARDS in it ? I followed with the online manual which says it is disabled by default there given some method to enable but I am not

David — this isn't the behaviour I see what QueryParser alone, unless you're driving it in a way I don't expect. In python: >>> import xapian >>> qp = xapian.QueryParser() >>> qp.add_prefix('subject', 'S') >>> str(qp.parse_query('subject:"and"', qp.FLAG_DEFAULT|qp.FLAG_BOOLEAN_ANY_CASE)) 'Query(Sand at 1)' >>> str(qp.parse_query('subject:"or"', qp.FLAG_DEFAULT|qp.FLAG_BOOLEAN_ANY_CASE)) 'Query(Sor at 1)' >>> str(qp.parse_query('subject:"not&quot...

I am working with version 1.2.7 and want to use stemming and synonyms. I use the perl-bindings and get some problems. First of all: the perl-bindings dont allow the QueryParser a third argument when calling parse_query! So i cannot set a default prefix (which perhaps is the solution to my problem, but later more) i have a simple testcase: 3 documents, every document only has one word: bike fahrrad (german bike singular) fahrraeder (german bike plural, umlaut replaced) i have build the database with one synon...

Hi, I'm using Xapian in Python2. I'm trying to replicate an analysis that somebody else performed in Lucene. To do that I need to do a search for a multi-word query in which particular fields are boosted - preferably at query time. That is, given a query like "the cat is lying on the mat" (with an OR operator, ignoring word positions but with stemming and stop words removed),

Hello, Do xapian has analyzer like EdgeNGram to use it for autocomplete. I am trying to use the auto completion using xapian. For example: e ex exa exam example etc.. so that we can get it.
