| virtual void StaticContext::setProjection | ( | bool | enabled | ) | [pure virtual] |
Sets whether document projection is enabled.
Document projection can be enabled or disabled at compile time, as well as overridden at runtime. By default document projection is enabled unless query complilation is unable to guarentee its correctness.
Document projection is an optimisation that uses query analysis to remove sub-trees from documents that aren't needed by the query. This results in substantially smaller memory usage and faster query times, but means that any subsequent querying on the results of an initial query can be wrong.
If you are hoping to perform further queries on the results of a query, you should turn document projection off to avoid incorrect results.
