    How to configure that a search for regular Latin letter will also search special character (e.g. Umlaut), and the opposite?


    There are 3 levels of normalization for special characters in Primo:

    1. The lowest are legacy mappings that are hardcoded in Java.
    2. The second are system-defined OTB files. They are located in /exlibris/primo/p4_1/ng/jaguar/home/profile/analysis/specialCharacters. (for example non_cjk_unicode_normalization.txt and all other txt files in that directory besides user_defined_unicode_normalization.txt).
    3. The third and the highest is user_defined_unicode_normalization.txt file. Each upper level supersedes the lower ones.

    To configure search an index for special characters please do the following:
    1. On all FEs and SEs server, edit user_defined_unicode_normalization.txt the following way:
    cd analysis/specialCharacters
    vi user_defined_unicode_normalization.txt

    Add codes in the following pattern:
    <Unicode> TAB <Unicode> (meaning Unicode=Unicode).
    e.g. if you want ? to be searchable for s, you’ll have to insert 0161 TAB 0073 -> ?=s
    Please note that you have to use TAB and not spaces.

    2. Deploy all
    3. Backup current indexes
    4. Run from be_bin
    5. Run indexing_and_didumean_and_hotswapping process

    Additional Information

    The above instructions do not affect the sort order in Primo.
