Wildcard searches with special character gives zero result

[Selvam Raman <se...@gmail.com>]

Solr version - 6.4.0

"title_en":["Chip-seq"]

When i fired query like below

1) chip-seq
2) chi*

it is giving expected result, for this case one result.

But when i am searching with wildcard it produce zero result.
1) ch*p-seq


if i use escape character in '-' it creates two terms rather than single
term.

Solr does not analyze queries with wildcards in it. So, with ch*p-seq,
it will search for terms that start with ch and end with p-seq. Since
your indexer has analyzed all tokens before, only chip and seq are in
the index.

See
https://solr.pl/en/2010/12/20/wildcard-queries-and-how-solr-handles-them/
for example.

If you really need results for such queries, I suggest to have a
copyField which is unstemmed and only tokenized on whitespaces. If you
then detect a wildcard character in your query string, search on that
field instead of the others.
