Module XapianIndexer

source code

Interface to the Xapian indexing engine for the Translate Toolkit

Xapian v1.0 or higher is supported.

If you are interested in writing an interface for Xapian 0.x, then you should checkout the following:

   svn export -r 7235 https://translate.svn.sourceforge.net/svnroot/translate/src/branches/translate-search-indexer-generic-merging/translate/search/indexer/

It is not completely working, but it should give you a good start.

Function Details [hide private]

_truncate_term_length(term, taken=0)

source code 

truncate the length of a term string length to the maximum allowed for xapian terms

Parameters:
  • term (str) - the value of the term, that should be truncated
  • taken (int) - since a term consists of the name of the term and its actual value, this additional parameter can be used to reduce the maximum count of possible characters
Returns: str
the truncated string

_extract_fieldvalues(match, (result, fieldnames))

source code 

add a dict of field values to a list

usually this function should be used together with '_walk_matches' for traversing a list of matches

Parameters:
  • match (xapian.MSet) - a single match object
  • result (list of dict) - the resulting dict will be added to this list
  • fieldnames (list of str) - the names of the fields to be added to the dict
