Hi, Just to confirm, are you asking about the following?
For a particular query, you have a list of documents, and for each document, you have data on the number of times the document was clicked on, added to a cart, and ordered, and you would like to use this data for features. Is this correct? If this is the case, are you indexing that data? I believe that the features which can be used for the LTR module is information that is either indexed, or indexed information which has been manipulated through the use of function queries. https://lucene.apache.org/solr/guide/7_5/learning-to-rank.html It seems to me that you would have to frequently index the click data, if you need to refresh the data frequently On Fri, Oct 26, 2018 at 4:24 PM Midas A <test.mi...@gmail.com> wrote: > Hi All, > > I am new in implementing solr LTR . so facing few challenges > Broadly we have 3 kind of features > a) Based on query > b) based on document > *c) Based on query-document from click ,cart and order from tracker data.* > > So my question here is how to store c) type of features > - Old queries and corresponding clicks ((query-clicks) > - Old query -cart addition and > - Old query -order data > into solr to run LTR model > and secoundly how to build features for query-clicks, query-cart and > query-orders because we need to refresh this data frequently. > > What approch should i follow . > > Hope i am able to explain my problem. >
