Changes

Speed up Search

With more and more Things, the Search service was slowing down massively.

Two Pull Requests (#275, #278) addressed this issue with the following changes:

  • add an index on _policyId and __policyRev for the thingEntities collection.
  • add the field _thingId to new documents in policiesBasedSearchIndex.
  • add an index on _thingId for the policiesBasedSearchIndex collection.
  • rewrite queries on policiesBasedSearchIndex to always look for the indexed _thingId first.

Since the access to the Search database was changed, data in policiesBasedSearchIndex needs to be migrated using the {% include file.html title="MongoDB migration script from 0.8.0-M2 to 0.8.0-M3" file="migration_mongodb_0.8.0-M2_0.8.0-M3.js" %}.
