Displaying search context
Hi,
I am indexing emails through Lucene. The body of the mails is stored in an
''Unstored" field. I also have a search interface setup which returns me all
Documents matching my query. What i need is to display a few lines from the
body of the mails where the queryTerm was found. How can this be achieved as
the body is just indexed but not stored.
Thanx

You can´t. If the indexing is unstored only the indicies of the words
are indexed and you cannot reconstruct the text from the field.

Thanx guyz for your prompt replies.

A nice suggestion but again as i'm indexing mails my Lucene Document has
fields like "Sender", "Subject", and "Content". Feeding the entire mail from
disk will also include meta-data which i need to exclude.
OR
If i extract the subject, content etc concating them as a string, and then
feed it to the highlighter it should work rite???

What you are doing is a good, scalable practice. You need to store
those email messages somewhere outside of Lucene, and use a unique id to
correlate the two. When you want to display relevant text for a search
result, find the file on disk, and pass it through the Lucene
Highlighter (see the Lucene sandbox). This will give you what you are
looking for, and it will scale well in the future.
