Subject Re: How to manage resource out of index?
Date Wed, 07 Jul 2010 06:15:43 GMT
hi li,

i looked at doing something similar - where we only index the text
but retrieve search results / highlight from files -- we ended up giving
up because of the amount of customisation required in solr -- mainly
because we wanted the distributed search functionality in solr which
meant making
sure the original file ended up the same filing system i.e. machine too!).

we ended up just storing the main text field too even though there was a
bit of text -- in the end solr/lucene can handle the index size fine and
disk space is cheaper than man-hours to customise solr/lucene to work
in this way!

that was our conclusion anyway and it works fine -- we also have
separate index / search server(s) so we don't care about merge time
either -- and as i said above - we use the distributed search so don't tend
to need to merge very large indexes anyway.
when your system grows / you go into production you'll probably split
the indexes too to use solr's distributed search func. for the sake of
query speed).

hope that helps,

bec :)
