Solr wilcard searches

I would like to search a book by its title. Lets say I have 2 books called

"Please do a wildcard search"
"Please do a deep search"

and then I do a solr wildcard search like the following:

{
  "responseHeader":{
    "status":0,
    "QTime":1,
    "params":{
      "q":"BOOK_NAME:\"Please*search\"",
      "indent":"on",
      "wt":"json"}},
  "response":{"numFound":0,"start":0,"docs":[]
  }}

I was expecting 2 books from this search, but the number of documents founds were 0

Reference I've found the wildcard searches:

I'm using solr 6.

Your query seems to be a phrase query, ie BOOK_NAME:"Please*search" rather than BOOK_NAME:Please*search. That will try to find the exact phrase Please*search

Also, I don't think the query will work unless you're indexing BOOK_NAME in a way that retains the entire title as a token. Either try indexing the field as a string or maybe try using the ComplexPhraseQueryParser

The ComplexPhraseQParser provides support for wildcards, ORs, etc., inside phrase queries using Lucene's ComplexPhraseQueryParser . Under the covers, this query parser makes use of the Span group of queries, e.g., spanNear, spanOr, etc., and is subject to the same limitations as that family or parsers

{!complexphrase inOrder=true}BOOK_NAME:"Please*search" or {!complexphrase inOrder=true}BOOK_NAME:"Please * search"
