Re: custom field tutorial
You seem to know what you want the words to map to, so index the map. Have one field for the word, one field for the mapped value, and at query time, search the words and return the mapped field. If it is comma separated, so be it and split it up in your code post search. Otherwise, same as Wunder, in my many years in search this is an odd request Anria Sent from my Samsung smartphone on ATT Original message Subject: Re: custom field tutorial From: Walter Underwood wun...@wunderwood.org To: solr-user@lucene.apache.org CC: What are you trying to do?

Re: custom field tutorial
Usually, people want to do the opposite - store the numeric code as a numeric field for perceived efficiency and let the user query and view results with the text form. But, there isn't any evidence of any great performance benefit of doing so - just store the string code in a string field. Also, your language is confusing - you say a single integer field that maps to the string field - do you actually want two separate fields? Is that the case? If so, just let the user query against either field depending on what their preference is for numeric or string codes. And your language seems to indicate that you want the user to query by numeric code but the field would be indexed as a string code. Is that the case? Maybe you could clarify your intentions. Sure, with custom code, custom fields, custom codecs, custom query parsers, etc. you can do almost anything - but... the initial challenge for any Solr app developer is to first try and see if they can make due with the existing capabilities. -- Jack Krupansky -Original Message- From: Anria Billavara Sent: Saturday, June 08, 2013 2:54 AM To: solr-user@lucene.apache.org Subject: Re: custom field tutorial You seem to know what you want the words to map to, so index the map.
