OutofMemoryError on enabling highlighting

                 Key: SOLR-1150
             Project: Solr
          Issue Type: Bug
          Components: highlighter
    Affects Versions: 1.4
            Reporter: Siddharth Gargate
             Fix For: 1.4

Please refer to following mail thread

I am testing with 2MB document size and just 500 documents. Indexing is working fine even
with 128MB heap size. But on searching Solr throws OOM error. This issue is observed only
when we enable highlighting. While indexing I am storing 1 MB text. While searching Solr reads
all the 500 documents in the memory. It also reads the complete 1 MB stored field in the memory
for all 500 documents. Due to this 500 docs * 1 MB * 2 (2 bytes per char) = 1000 MB memory
is required for searching.

This memory usage can be reduced by reading one document at a time.
