I did state two ways in my last email, but just to re-iterate: (1): The filter reflects a query constructed from lines in a text file. If some other application modifies the text file, that filter is now invalid. (2): The filter reflects the results of an SQL query against a separate database. If someone inserts a new value into that table, then that filter is now invalid. Case 1 occurs for things like word lists. Case 2 occurs for things like tags. Neither of these would ever be possible to implement purely using Lucene, so it is a fact of life that they will become invalid for reasons other than the reader changing.
