I need to retrieve all the documents from my index, NOT containing a few keywords. I dont require ranked results, instead just the set of documents is what I am after. Eg: Let the terms to exclude are: Term1, Term2, Term3 Then, I need all documents not containing these terms. Is this operation possible in Indri ? I tried using #filrej as follows: #filrej(#syn(Term1 Term2 Term3)) However, this query seems to be wrong, as filrej requires a second argument for ranking, which in my case is none. Any...

I need to get the occurences of certain query words in a document for a small set of documents. I cannot use expressionList, as it return all the documents and positions from the collection, containing the term, which is very slow. Is there any built-in functionality of achieving the same? Someway of limiting expressionList to a small set of documents. Basically, like in runQuery we can specify the number of docs to consider for query, can we do the same for expressionList. Can DocumentVector class...

How can I execute the following boolean query on Indri: (Stana or Katic) AND (Jon or Huertas) AND (co-stars or colleagues) I need to get all the documents, which match the above condition. I tried formulating the query like this: #combine(#band(#syn(Stana katic)) #band(#syn(Jon Huertas)) #band(#syn(co-stars colleague))) I also tried formulating it like this: #band(#syn(Stana katic) #syn(jon huertas) #syn(co-stars colleague)) However, I am not sure of these approaches and their correctness. Please...
