Hello all,
During concurency test, i.e. indexing and searching simultaniosly,
Searcher stumbled with following error:
java.lang.RuntimeException: no terms in field modified - cannot determine
sort type

Indexer was optimizing and closing after every 300 entries.
Searcher did query every second: hits = ms.search(query,new Sort("modified",true));
where "modified" is in DateField.timeToString(modified)) format and query
like "+contents:novartis"
The values for field "modified" are definitly existing.
On Indexer side no exceptions took place.
Both processes used the same lockDir.
Searcher works smartly on created index.
Please help.
Have a nice day
J.
