This character is classified by Unicode as punctuation: http://www.fileformat.info/info/unicode/char/00a7/index.htm Almost any example field type for full-text search that you're likely to encounter is going to be designed to split on punctuation and remove it from the token stream. That's one of the most common things that full-text search engines do. You're going to need to design a new analysis chain that *doesn't* do this, apply the fieldType containing that analysis to your field, restart/reload, and reindex. Designing analysis chains is an art form, and tends to be one of the hardest parts of setting up a production Solr install. It took me at least a month of almost constant work to settle on the schema design for the indexes that I maintain. All of the "solr.TextField" types in my schema are completely custom -- none of the analysis chains in Solr examples are in that schema. Thanks, Shawn
