Re: Indexing tempary data on lucene

[Chris Hostetter <ho...@fucit.org>]

building a temporary index would certainly work, but it's a question of 
how efficient it would be (ie: how many users do you have, how often do 
they log in, how long does it take to build a typical index, how many 
concurrent users will you have, etc...)

one solution i've seen to a problem like this was to have a custom 
SearchComponent that did an external lookup to get the list of freinds, 
then for each friend did a search to get the DocSet of all their documents 
(letting them get cached in the filterCache) and computed the union of all 
those DocSets, and added that union as a filter for use by the 
QueryComponent.

not sure if that type of approach will scale well to the number of users 
you are dealing with.

: I have a list of public profiles of my site user's on solr index. There is
: also a community around them, which is currently not their in Index.

: While searching, I have to give an option to search only my community
: (friends and friends of friends). I could do it from data base query or
: storing connection graph in memory but here I loose power of Solr Analyzers,
: tokenizers and filters. 
: 
: Alternatively, I am thinking to store this relation temp in some other Solr
: instance (running on a separate machine) and use it for search. I.e create
: this index async when user logs in and destroy when user logs out.
: 
: So when user searches for a profile the application will merge the results
: from two indexes and returns unique users.
: 
: Is this a practical/scalable solution? If yes, what performance
: consideration, I should look for this new solr instance? For merging should
: I built an application over solr or solr provides any way of merging results
: from multiple indexes?
