This controls how the query parser will apply the stemming algorithm. The default value is STEM_NONE. The possible values are:
<br>
    * STEM_NONE: Don't perform any stemming.<br>
    * STEM_SOME: Search for stemmed forms of terms except for those which start with a capital letter, or are followed by certain characters (currently: (/@\<\>=*[{\" ), or are used with operators which need positional information. Stemmed terms are prefixed with 'Z'.<br>
    * STEM_ALL: Search for stemmed forms of all words (note: no 'Z' prefix is added).<br>

Note that the stemming algorithm is only applied to words in probabilistic fields - boolean filter terms are never stemmed.<br>
