Hi, all:
I met a problem with solr. I have docs containing characters like []?! etc. I want to search such docs. Documents say

Escaping Special Characters

Lucene supports escaping special characters that are part of the query syntax.

The current list special characters are

&& || ! ( ) { } [ ] ^ " ~ * ? : \ To escape these character use the \ before the character. For example to search >for (1+1):2 use the query:

(1+1)\:2

But on solr Ui Admin, It doesn¡¯t work as documents say. Result show below

Where is the problem? Thank you for your help!

Best Wishes!

Hi,

Can you post your question over at solr-user@lucene.apache.org mailing list?
And FYI the image attachement did not make it thgough. Can you upload it somewhere (Dropbox?) and include the link?
Can you also try your query directly in the browser address bar, not in the Admin UI? e.g. http://localhost:8983/solr/techproducts/select?q=test
