Configure Stop Words, Synonyms, and Character Mappings

Configure Stop Words, Synonyms, and Character Mappings

When you perform a search, MDM can ignore common words such as "and", "an", and "is". MDM can also search for synonyms of the search string. For example, when you search for "William", the search result can include the synonyms "Will" and "Willy".
To configure common words to ignore or include synonyms in search results, Informatica provides text files that contain stop words and synonyms, or you can configure your own.
To use the default Elasticsearch analyzers for languages such as Chinese, Japanese, and Korean, Informatica provides a mappings file,
mapping-FoldToASCII.txt
. The character filter of these default analyzers uses the mappings file to convert alphabetic, numeric, and symbolic characters that are not in the Basic Latin Unicode block to their ASCII equivalent.
To get the
stopwords.txt
,
synonyms.txt
,
stopwords_ja.txt
, and
mapping-FoldToASCII.txt
 files, contact Informatica Global Customer Support.
To configure stop words, synonyms, and character mappings, perform the following steps:
  1. Create an
    analysis
     directory in the following location:
    <elasticsearch installation directory>/config
  2. Copy the
    stopwords.txt
     and
    synonyms.txt
     files to the
    analysis
     directory.
  3. To configure stop words for languages such as Japanese, create a
    lang
     directory in the following location:
    <elasticsearch installation directory>/config/analysis
  4. Copy the stop words files for other languages, such as
    stopwords_ja.txt
    , and the
    mapping-FoldToASCII.txt
     file to the
    lang
     directory.
