Good afternoon to all Terrier users,
I read the documentation of Terrier 3.5 about the two types of indexing but I couldn't get the main differences of the two methods.
What I understood is that the Two-Pass indexing create the direct file to store some temporary results while Single-Pass does everything with the memory.
Thus, Two-Pass allows to use directly some retrieval models that use the direct file, whereas you have to create the direct file "manually" if you used Single-Pass and want to use these retrieval models.
Here comes my question (finally) : are these differences the only differences between the two methods?
or does the two methods are also different in terms of performance for the quality of the information retrieval process (meaning do the two methods have different impacts on measures such as precision, recall...)?
Thanks for your time, your answer may save me some usefull time
