> LUCENE-2605 introduced the classic query parser option to not split on 
> whitespace prior to performing analysis.
> From the javadocs for QueryParser.setAutoGeneratePhraseQueries(): 
> bq.phrase queries will be automatically generated when the analyzer returns 
> more than one term from whitespace delimited text.
> When splitOnWhitespace=false, the output from analysis can now come from 
> multiple whitespace-separated tokens, which breaks code assumptions when 
> autoGeneratePhraseQueries=true: for this combination of options, it's not 
> appropriate to auto-quote multiple non-overlapping tokens produced by 
> analysis.  E.g. simple whitespace tokenization over the query "some words" 
> will produce the token sequence ("some", "words"), and even when 
> autoGeneratePhraseQueries=true, we should not be creating a phrase query here.
