IllegalArgumentException: attempt to access a deleted document

[Peter Kim <pk...@cymfony.com>]

Hi,

I'm getting this error from trying to access a document in my custom hit
collector:

java.lang.IllegalArgumentException: attempt to access a deleted document
        at
org.apache.lucene.index.SegmentReader.document(SegmentReader.java:235
)
        at
org.apache.lucene.index.MultiReader.document(MultiReader.java:108)
        at
org.apache.lucene.search.IndexSearcher.doc(IndexSearcher.java:74)
        at
org.apache.lucene.search.MultiSearcher.doc(MultiSearcher.java:66)


Does anyone know why I'm getting this error? Shouldn't the ids passed to

HitCollector.collect(int id, float score) all be valid? Or are deleted
ids not ignored?

I noticed one way to get around this is to use IndexReader.isDeleted()
to check if it's deleted or not. The problem with that is I only have
access to a MultiSearcher in my HitCollector which doesn't give me
access to the underlying IndexReader. I don't want to have to open an
IndexReader in my custom hit collector to use its isDeleted() method.

Anyone know any workarounds?

Thanks!
peter

Check out the MultiSearcher methods subSearcher() and subDoc().  If you 
keep an array of the IndexReaders that your MultiSearcher searches, then 
you can use:

readers[searcher.subSearcher(doc)].isDeleted(searcher.subDoc(doc))

Hope that helps.

Doug
