[chef-dev] Qustions about Chef searching module(couchDB/solr)

[Xiaoding Bian Cloud Services RANDD - 72410 < >]

Hi chef-devs:

    I am an engineer from VMware, recently we met a problem when using Chef's searching feature, so I'd like to know if 

anyone can share some knowledge/details about searching module's implementation(we are using Chef-0.10.8). 

   Basically, Chef provides two operations like  "search(:node, "name:node01")" and "node[:name]="node01", node.save".

   I'd like to know when executing node.save or search function, what exact actions chef-server will do, for example:

   (1)When and How does Chef read data from couchdb and update solr indexes?

   (2)when updating solr indexes, does Chef fetch the whole data bag or just the data changed recently.

   (3)If we tend to run search function very frequently, every 10 seconds for example, and the databag maintains hundreds 

       of records, is there potential performance concerns about chef-server/couchdb/solr from your perspective?

Thanks a lot,
