Social Search?

Elastic Stack Elasticsearch
1

Hello,

I'm kinda new to elasticsearch, but so far, it's been a really good
ride ! :slight_smile:

Now I i'd like to boost results that according to a social graph...
For example, if some content is from my friend or my friend's friend,
I'd like to boost it.

How would that be possible using elasticsearch ?

Would I need an index for each users ?
How would you guys set the mapping ?

Thanks a lot !

that sounds like possibly a custom score:

But be careful, friends of friends can become pretty big pretty quick :smiley:

Either attack that via custom score or a filter query which includes
all friend and friends of friends. For jetslide / jetwick(open source)
I've implemented this that way.

But as Paul noted this can become quite big. A solution would be to
attach a marker array "forUsers" to every document. This way you have
hopefully less big arrays in the documents and one a simple term
filter while searching. You could also do some boosting e.g. add
"twitterUserName":9 to the document and then do a sort or boost
against that field...

Peter.

Thanks a lot for both replies! :slight_smile:

It's still kinda fuzzy for me...
The documentation also talks about a different approach,
one where there would be an index for each of users.
Do you guys know what would be indexed in there ?
Only user's friends or also user generated content ?

query.html)

Thanks again for your help.
