dalius created SOLR-3608:
----------------------------

             Summary: Spellcecker: String index out of range: -1
                 Key: SOLR-3608
                 URL: https://issues.apache.org/jira/browse/SOLR-3608
             Project: Solr
          Issue Type: Bug
          Components: spellchecker
    Affects Versions: 3.6
         Environment: Ubuntu 11.10 x64
            Reporter: dalius


Spell check component throws StringIndexOutOfBoundsException on multiterm search.

Stack trace: 
{code}
SEVERE: java.lang.StringIndexOutOfBoundsException: String index out of range: -1

I have dug some debug info at org.apache.solr.spelling.SpellCheckCollator:69
{code}
      String collationQueryStr = getCollation(originalQuery, possibility.getCorrections());
{code}
originalQuery is "casa saja"
possibility is "rank=0     casa>cal (-1)     saja>sala (-1)     casa saja>casa de
(-1)"

The replace function fails on 3rd correction "casa saja>casa de (-1)". I hope this makes
any sense.
