Page Comparison

Note you can also get data from the API directly, see the examples in the query documentation. The only difference is that the documents are returned in a field called "data" instead of "documents", so it will have to be renamed by hand before running the test harness.

It is recommended to use an indexed field when trying to select a small % of large communities:

• Document metadata:
  • "sourceKey"
  • "_id"
  • "url"
  • "entities.index"
• Document content:
  • "sourceKey"
  • "url"
• Entity features
  • "index"
  • "disambiguated_name"
  • "alias"
• Association feature
  • "index"
• Custom metadata tables:
  • "_id"
  • Any fields specified for sorting

eg in the example above, "source" is not indexed and therefore would perform a full scan within the community which for larger communities is sub-optimal. A future release will allow use of the full query API to provide more flexible queries at high speeds.

Also note: If running in standalone mode you cannot use Infinit.e-style queries, or "$srctags" or "$caches" modifiers.
