Hi! Our national alphabet (Latvian) consists of letters that are subset of Latin alphabet. In addition to them there are some Latin letters with diacritics that are considered as separate significant letters (used in sorting, etc.). I hope you see them correctly in this post — ā ē ī ū ŗ ļ ķ ņ ģ š ž.

By searching our historical EX archive through a SourceOne Search page I discovered that the results mostly are not consistent when searching for Latvian words that contain these diacritics — almost always some messages are not included. Strangely, the situation can be improved when the Latvian word is ORed with a word, that has the diacritics replaced with respective Latin letters. For example, the search for a phrase could look like: "meklēšana vēstuļu arhīvā" "meklesana vestulu arhiva". It's still not perfect, because EX/SO indexes letter 'Š' as a significant character and words with that character are sometimes returned but sometimes they don't when using the search above. I do not have the Native archive in place yet, so I can't test it if that behaves any better.

Is there anything I can try to improve the searches?

And what is the apropriate (system) locale to set in SourceOne server's regional settings in our case?

Environment:

  SourceOne v6.7,

  EmailXtender v4.81.2518,

  Exchange 2007,

  Archive and indexes starting from year 2006.

Best regards,

Kaspars
