i need a document term matrix to initialize a neural network, that i want to use to integrate user feedback in the retrieval process.
until now, i am using a slightly modified class of the IndexHTML example.
how can i create an index of all the terms in a collection without "term" and "Term" being indexed twice?
in the example, a standard analyzer is used, and in the documentation it sais :
Filters StandardTokenizer with StandardFilter, LowerCaseFilter and StopFilter.
So, why do i get double entries for terms in upper- and lower case writing?
Regards.
Thomas
