Enis Soztutar commented on NUTCH-393:
-------------------------------------
Also IndexingException is catched by the Indexer, in which case the whole
document is not added to the writer (the function returns).
Indexer : 334
try {
// run indexing filters
doc = this.filters.filter(doc, parse, (UTF8)key, fetchDatum, inlinks);
} catch (IndexingException e) {
if (LOG.isWarnEnabled()) { LOG.warn("Error indexing "+key+": "+e); }
return;
}
IndexingException should be cought in the IndexingFilters.filter(), so that
when an IndexingException is thrown in one indexing plugin, the other plugins
could still be run.
> Indexer doesn't handle null documents returned by filters
