i don't know why that works today:
I can know make a visulation of count of words in the attachement.content , but this visulation dosent respond in Lucene search , "it display always all the count of words".
what i want is when searching a word ,the visulaztion respond by displaying just the count for these word.
even if i add a filter that dosen't work.
I think the problem here because the data is unstructured ( not in rows)
also the count isn't true for example the word "un" is repeated 3 times but the visuliztion shows just 1 and for all of words
