DefaultIndexStrategy implements indexing of PersistentObject values and might be customized by overriding the isIncluded and/or enhanceDocument methods.
Which values will be added to the index is controlled by the tag SEARCHABLE (see AttributeDescription) in the following way:
- If no value is tagged as SEARCHABLE, all values will be included in the index
- If at least one value is tagged as SEARCHABLE, only values with this tag will be included in the index
This allows to exclude certain values from the index by omitting the tag while setting it on the other values.
