[Xapian-discuss] pure data xapian search engine

[Jonathan Wilkes]

Hi list,
     I'm currently refactoring Pure Data's search function to use Xapian.
Mostly it works well, without a lot of finessing.

The one sticking point is with indexing Pd "objects", which are typically
letters, numbers, hyphens, underscores, and sometimes a trailing tilde,
with no whitespaces.
So "clip" is one object, and "clip~" is a different object.

I can index these terms just fine, and I'm currently using prefix XO to
make the clip~ object searchable using "object:clip~".  The problem
is that the query parser is removing the tilde, even if I set the stemming
strategy to $xapian::QueryParser_STEM_NONE (using the tcl bindings).

How do I tell the query parser to keep the tilde?  I suppose I could
change all instances of object~ to object_tilde in both the index and
the user input, but since they go into the index with no problem is there
a way to tell the parser to keep them for the search?

Thanks,
Jonathan
