1. A method comprising: accepting a request to a wild card auto completion service including an input term at least partly in a target language and at least partly in an initial language, wherein the initial language and the target language are two different languages, the service employing a syntax to accept the input term including zero to multiple wild card characters in the target language or in the initial language in a first part and a delimiter indicating a second part, the second part comprising the target language or the initial language such that: if the language of the first part includes the initial language, the second part includes the target language and if the language of the first part includes the target language, the second part includes the initial language, and the second part identifying at least one of a context or a domain for the wild card auto completion service; identifying an initial-target language pair for the request; aggregating two or more consecutive homogenous wild card characters, wherein the aggregating comprises replacing the two or more consecutive homogenous wild card characters with a single wild card character of a same type as the homogenous wild card character; parsing the input term to identify a pattern of the input term; selecting a matcher corresponding to the pattern of the input term; matching the input term to an entry using the matcher selected; and returning the entry.
