[Exist-open] check if a index for a document exists !

[Dulip W. <wit...@as...>]

Hi,

With ft:remove-index('xyz'), I can remove the entry from  the lucene
index.

Is there a function in eXist to check, if there is already a index for a
binary file in the database?

In the  functional documentation, I don't find it.
http://demo.exist-db.org/exist/functions/ft

If then , it would be helpful for me to write a function, which adds new
documents into the lucene index, without deleting the index and
regenerating whole index which is processor and memory intensive,
specially when I have a collection of big pdf files which are over 500
MB :-). 

Best,
Dulip
