I would start by suggesting that you create an indexing/querying analyzer specifically for the field you know has this format.
Otherwise, I think your likeliest path to success, I think, is somewhere in the character filters domain. Character filters are applied to the string before the tokenizer: http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/custom-analyzers.html One possibility here is a pattern replace char filter. http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/analysis-pattern-replace-charfilter.html If you can write a matching pattern for all of the allowed values of this field, and replace them with just the number, apply that pattern to your indexing and searching, then you are only dealing with searching for the numbers. You may need a different character filter for the search analyzer, though, since you are allowing for more formats than are found in the source document field.
