Hi, I recently read about payloads in the Apache Solr 4 Cookbook and would like to know if this is the right solution for my problem or if other methods are more suitable.
Generally, I need to perform fulltext search in a field (including highlighting) where I need metadata per token in the search result, but I do not need to search in that metadata. I have documents containing data (not natural language), where each data entry contains multiple metadata informations. An example with a sentence and as XML-like structure could be <meta attr1="val11" attr2="val2" attr3="val3">This</meta> <meta attr1="val13" attr2="val7" attr3="val3">is</meta> <meta attr1="val16" attr2="val22" attr3="val3">one</meta> <meta attr1="val14" attr2="val2" attr3="val3">sentence.</meta> Additionaly there exist some fields per document that i need for faceting etc. (id, category, timestamp etc.) When searching, I want to search only in "This is one sentence.", a search for "attr1" or "val3" should give no results. However, when searching for "one" in the search response I need to know attr1="val16" attr2="val22" and attr3="val3". My first intuition when creating the schema was to create a multiValue field "content" containing each word in the document. Then I add attr1, attr2 and attr3 as payload to each word/token. Is this the right way to use payloads? Or is there a better solution for such a task? I imagine this to be a common use case: searching in a "cleaned" version of the data and returning the original one. Could anyone please provide suggestions on how to tackle such a task? The book and the Solr wiki pages did not lead me to anything that I could immediately identify as a solution to my problem. If the proposed solution depends on the data: each document might have 3-8 additional attributes, and there might be between 100-10000 tokens per document.
