Hi All, I want to be able to do a search for a term in all fields in a document.
One way this can be done is to put every element of a document in the default field (or I guess any other single named field) as well as separate fields in which those elements belong. So for example if for my documents I had the following fields: A, B, C, D and E If I then set up a field called All And for all documents I processed as well as putting the elements of that document in A, B, C, D and E I would also put them as a concatenation into All as well. One problem with this is that if for a particular document I had these values for my five fields: A -> Hello B -> How C -> Are D -> You E -> Mate (All -> Hello How Are You Mate) Then a search for "How Are You" in All would return true when no single field contains this string which is not ideal. Another problem with this is that it would double the size of the index (unless Lucene does something clever here). A way to solve the original issue is to convert the search for "How Are You" into this: A:How Are You OR B:How Are You OR C:How Are You OR D:How Are You OR E:How Are You This solves both the problems of the solution where we set up the All field (viz. increasing the size of the index and bringing back more results than we should). However, this solution also has it's drawback and that is that now we have gone from a simple query to a complex ANDing of all fields in the document. My question is this: is there a third way?
