Properties¶

The response includes a key named after each changeset property requested in the query or, if no changeset properties were explicitly requested, then the response includes an entry for every changeset property of the item.

If the query request included the highlighting criterion, then any highlighting will be applied to the returned changeset property values.

The order of the dictionaries in the response array is in the same order as the items return in the query response.

The properties are stored in a disk-based database and retrieve on an as-needed basis. To increase concurrency, the engine will maintain a cache of items in a least recently used item cache. You can determine the size of the cache, in number of items, using the Settings page of the Admin Tool.

Transparensee Systems reserves the right to alter or remove this API in any way and at any time in the future. It provides this feature solely for debugging purposes.

Note: queryTime, propertiesTime and highlightTime all appear as top-level query response fields. The other explain responses are described here.

See: Explain for a description of the explain request API.

renderParmeters¶

The renderParameters response is used primarily by the Transparensee jQuery widget suite. It returns a single field, “renderParameters”.

See: Render Parameters for a description of the renderParmeters request API.

Sample responses:

{
  "renderParameters": "startIndex=0&pageSize=4&exactSize=9&totalSize=9 \
      &itemIds=CheapHeavyCircle+CheapLightCircle+CheapTriangle+ExpensiveHeavySquare \
      &exactMatches=1111"
}

{
  "renderParameters": "startIndex=0&pageSize=4&exactSize=9&totalSize=9 \
      &itemIds=CheapHeavyCircle%2CCheapLightCircle%2CCheapTriangle%2CExpensiveHeavySquare \
      &exactMatches=1111"
}
