Hi,

Can Lucene support wildcard searches such as the ones shown below?

Indexed value is "XYZ CORPORATION LIMITED".

XYZ CORPORATION LIMI*
XYZ CORPORATION *MIT*
XYZ *PORAT* LIMI*
*YZ CORPO* LIMITE*

In other words, the flexibility for the user to provide a wild card at any=
=20
position, in a situation where they aren't sure about the exact value.=20
Ignoring the performance aspect, please suggest if it is even possible. If=
=20
yes, please provide further inputs on how to approach it such as Analyzer /=
=20
Tokenizer to consider, whether PhraseQueries can be formed etc.

Any input is greatly appreciated.

Regards,
Raghu
