SOLR搜索问题的野性

Question

I have a search query in SOLR with wild char . My need is I need to set the character length. Is it possible in SOLR ?.

For Eg

status:(d*mo) - I need to get only a word with 4 character, ie one character should be replaced in second position

Please help

Thanks

Great ! One more doubt. Do we need to put back slash before "?" ? ie does d\\?mo is needed ? Also in SOLR whether single slash is supporting ? For Eg : Can I check the word "jack's" ?

Answer 1

There are two forms of wildcard character:

• asterisk ("*") which will match zero or more arbitrary characters and
• question mark ("?") which will match exactly one arbitrary character.

If you want to check for single arbitary character you should use ?

So d?mo would match words with 4 characters with second character being the variable part.
