--------------------------------------
{quote}
query: '(john OR jonathon) smith~0.3 order*' order:sell "stock market"
{quote}
Would be parsed as follows (shown as equivalent XMLQueryParser syntax)
{code:xml}
<BooleanQuery>
<Clause occurs="should">
<SpanNear >
<SpanOr>
<SpanOrTerms>john jonathon </SpanOrTerms>
</SpanOr>
<SpanOr>
<SpanOrTerms> smith smyth</SpanOrTerms>
</SpanOr>
<SpanOr>
<SpanOrTerms> order orders</SpanOrTerms>
</SpanOr>
</SpanNear>
</Clause>
<Clause occurs="should">
<TermQuery fieldName="order" >sell</TermQuery>
</Clause>
<Clause occurs="should">
<UserQuery>"stock market"</UserQuery >
</Clause>
</BooleanQuery>
{code}
> Wildcards, ORs etc inside Phrase queries

>
> An extension to the default QueryParser that overrides the parsing of
> PhraseQueries to allow more complex syntax e.g. wildcards in phrase queries.
> The implementation feels a little hacky - this is arguably better handled in
> QueryParser itself. This works as a proof of concept for much of the query
> parser syntax. Examples from the Junit test include:
> checkMatches("\"j* smyth~\"", "1,2"); //wildcards and fuzzies
> are OK in phrases
> checkMatches("\"(jo* -john) smith\"", "2"); // boolean logic
> works
> checkMatches("\"jo* smith\"~2", "1,2,3"); // position logic
> works.
>
> checkBadQuery("\"jo* id:1 smith\""); //mixing fields in a
> phrase is bad
> checkBadQuery("\"jo* \"smith\" \""); //phrases inside phrases
> is bad
> checkBadQuery("\"jo* [sma TO smZ]\" \""); //range queries
> inside phrases not supported
> Code plus Junit test to follow...
