The false labelling of files as 'Partial indexing only' was a bug in that version of the program. It was fixed in Build 3286.
If you're still getting the warning then the source documents contain too many terms for the default memory settings.
Indexing memory usage
During the indexing of a document the indexer maintains a list of unique terms within the document, therefore lots of unique terms requires lots of memory. Internally the indexer has four different memory settings:
- 1: Very high
- 2: High
- 3: Normal (default)
- 4: Low
The setting determines the maximum amount of RAM, as a percentage of total RAM, the indexer can use.
At present the only way to change these settings is via the config_v9.xml file, located in the Configuration -> Folders -> Config folder. To increase the RAM usage to maximum, add/modify the IndexMemMgr section and set the value to '1' for both MaxRamUsageType and MaxRamPerDocType :
<MaxRamUsageType n="1" />
<MaxRamPerDocType n="1" />
Since the indexer can concurrently index documents on separate threads the indexer may throttle the number of threads if it decides the host system's RAM could potentially be exhausted.
