lucene - Which field type should I use to store true/false values? -


i want store boolean value, not sure field type use.

so theoretically:

doc.add(new ????("numeric", true) doc.add(new ????("alphatic", true) doc.add(new ????("alphanumeric", true)

i querying using these boolean field types like:

  1. search numeric only
  2. search alphabetic only
  3. search alphanumeric

any comments on best approach? (speed/effeciency important ofcourse)

i think, stringfield job since don't want values - true or false tokenized. also, third parameter in constructor , can choose store field or part of index without getting stored.

javadoc ,

a field indexed not tokenized: entire string value indexed single token. example might used 'country' field or 'id' field, or field intend use sorting or access through field cache.

new stringfield("numeric", "true", store.no)....etc.
