Lucene's IndexWriter allows users to update documents by Term via this method signature: void updateDocument(Term term, Document doc)
But what about updating them by Query? Like so: void updateDocument(Query query, Document doc) 1) How can this be done? As far as I know there is no such method signature right now. In my data there is no way for me to uniquely identify a document for update without matching more that one term, so I really need to use a Query. 2) Would it be better to change the initial underlying indexing process such that the multiple fields (that can identify a unique document) will be concatenated into one string and indexed? Then that field can be used for identification when doing updates? Is this the common practice? 3) Or, would it be better to use the Query I have to search for the docID that the Lucene index assigns to the data inside it and then try to update based on that? Will I get in trouble here somehow? Any tips are appreciated.
