I'm having trouble translating from C++ to perl objects. The TermIterator class looks like to get a set of terms in a document you might have C++ code like: Enquire::TermIterator termIt =enquire->get_matching_terms_begin(id); for(;termIt != enquire->get_matching_terms_end(id);termIt++) { string term = *termIt; } Or something similar. However when I attempt to translate that into perl, I am trying:( I am working in the blind here) foreach...

.... Hi Olly -- the following piece of tested code in omega/weight.cc hopefully achieves what we intend to do. It works fine for all tests. Please let me know what you think. if (startswith(scheme, "pl2")) { const char *p = scheme.c_str() + 3; if (*p == '\0') { enq.set_weighting_scheme(Xapian::BM25Weight()); return; } if (C_isspace(*p)) { Xapian::Registry reg; const Xapian::Weight * wt = reg.get_weighting_scheme("Xapian::PL2Weight"); enq.set_weighting_scheme(*wt->set_parameter_values(p)); return;...

The Database object itself effectively does (it works in a snapshot of the state of the database when you open it, or last called reopen() which updates that snapshot to what's currently committed). However we don't currently have any locking of the snapshots that readers are...

Thanks, the Centos 6 repos don't have that rpm and the http://xapian.org/download page seems to only cover the XS bindings, if I am reading this correctly: But I was able to remove the rpm packages and compile and install the core and swig from source.

In other words, is it possible to avoid duplicates if new documents are inserted into the DB by another process in-between ->get_mset calls when reusing Xapian::Enquire objects? I do some expensive processing on each mset window, so I always limit the results to limit heap usage even if I'm planning on going through a big chunk of the DB: $mset = $enq->get_mset(0, 1000); do_something_slow_with_mset($mset); $mset = $enq->get_mset(1000, 1000); do...

I've been using SWAT to configure SAMBA for file and print serving at the organization I work at, and I ran into a hitch. The print command we use in smb.conf is "enq -r -c -o"-dc" -P%p %s". After SWAT updates (and when it starts up), the print command in the SWAT display is shortened to "enq -r -c -o". The proper print command is saved into smb.conf, but it needs to be checked every time we make changes to smb.conf via SWAT, as SWAT sho...

Hi All, I would like to take a doc in the xapian DB and find all related documents by relevance e.g. so when you view one document it says "Related entries X Y Z". I'm aware of the "Morelikethis" Lucene plugin that is supposed to do something like this, by generating a query from a document based on term frequency. Has anyone developed a tool to generate a query from a

...n the iterator is created (it is conceivable this might > be different for a new database backend in the future I suppose). Oh wow. In Perl, I only had a retry_reopen wrapper only around the get_mset call to reopen the DB because documents get added frequently: my $mset = retry_reopen(sub { $enq->get_mset(0, 1000) }); for my $m ($mset->items) { ... } But the above was actually unsafe from modifications and I should be doing the following?: my $mset = retry_reopen(sub { $enq->get_mset(0, 1000) }); my $cur = retry_reopen(sub { $mset->begin }); my $end = retry_reopen(sub...

...'t reproduce the bug above. In fact, I don't use a "join(get_matching_terms())" as smoketest do, but iterate with get_matching_terms_begin and get_matching_terms_end.
