Hi Guys I have a Solr application searching on data uploaded by Nutch. The search I wish to carry out is for a particular document reference contained within the "url" field, e.g. IAE-UPC-0001.
The problem is is that the file names that comprise the url's are not consistent, so a url might contain the reference as IAE-UPC-0001 or IAE_UPC_0001 (ie using either the minus or underscore as the delimiter) but not both. I have created the query (in the solr admin interface): url:"IAE-UPC-0001" which works (returning the single expected document), as do: url:"IAE*UPC*0001" url:"IAE?UPC?0001" when the doc ref is in the format IAE-UPC-0001 (ie using the minus sign as a delimiter). However: url:"IAE_UPC_0001" url:"IAE*UPC*0001" url:"IAE?UPC?0001" do not work (returning zero documents) when the doc ref is in the format IAE_UPC_0001 (ie using the underscore character as the delimiter). I'm assuming the underscore is a special character but have tried looking at the solr wiki but can't find anything to say what the problem is. Also the minus sign also has a specific meaning but is nullified by adding the quotes. Can anyone suggest what I'm doing wrong? Many thanks Paul
