Compacting and Building Dictionaries

The dictionary capabilities include compact and building policies.

  • Compact policies: Dictionary data is regularly compacted after N import operations and/ or N seconds, to keep a single file per resource.

  • Build policies: Dictionaries are regularly rebuilt after N compact operations and/ or N seconds to be up-to-date.

The following procedures explain how to configure compact and build operations.

Compact Individual Dictionaries

  1. In the Administration Console, go to Index > Linguistics > Dictionaries > Dictionary > dictn > Configuration.
  2. Select Enable compact and specify the compact policy.
    • Choose to compact when N import streams have been done since the last compact operation.
    • Choose to compact every N second.
  3. Click Save and Apply.

Fine-Tune the Compact Size

  1. Edit the <DATADIR>/config/Dictionary.xml file
  2. Add a FrequencyCompactFilter to the CompactPolicies node, as shown in the following example. 

    <dict:CompactPolicies disjunctives="true">
  <dict:ImportCountCompactPolicy countThreshold="1"/>
  <dict:FrequencyCompactFilter lang="fr" minFrequency="10"/>
</dict:CompactPolicies>

    In this example, the compact file is lightened of all French terms that do not have at least 10 occurrences.

Build Individual Dictionaries

  1. In the Administration Console, go to Index > Linguistics > Dictionaries > Dictionary > dictn > Configuration.
  2. Select Enable build and specify the build policy.
    • Choose to build when N compact operations have been done since the last build operation.
    • Choose to build every N second.
  3. Click Save and Apply.

Force a Compact and a Build Operation

Sometimes, you do not want to wait for the end of a compact or a build operation, and start them at once.

  1. In the Administration Console, go to Index > Linguistics > Dictionaries.
  2. In the Dictionary status panel, click Compact & Build for the dictionary you want to compact and build immediately.
  3. Click Save and Apply.
