This issue is for the addition of some log4j tracing and a configuration item associated with development in jena-text. The tracing is in TextQueryPF and TextIndexLucene to track calls to exec and the subsequent processing as well as the add, update and delete of Lucene documents.
The trace-level is used so as to not interfere with the current debug-level items that are familiar to developers.
The configuration item text:cacheQueries false ; on text:TextIndexLucene allows to bypass use of the queryCache in TextQueryPF.query(...) during development. This configuration item is not for general use and need not be documented further.
