      Description

      Now that we've upgraded Hibernate to a version that supports hibernate search (in OpenMRS 1.9) we should look into removing our own mediocre search index implementation (concept_word) and do something more powerful and faster that relies on hibernate search, or lucene.

      A powerful and important feature of concept searching is the inclusion of stop words and equivalent words. Any searching solution should incorporate these features.

      • stop word - words that should not be indexed (e.g., a, and, the, ...)
      • equivalent words - variations of common terms (e.g., heart, cardiac, myocardial, myocardium). Ideally, these are normalized to a single term in indexing and searching so that, for example, a search for "heart" and "cardiac" would return identical results. This can significantly reduce the need for synonyms containing these equivalent words.
