Vikas Saurabh commented on OAK-3769:
Yes, thinking further, I also thought that exposing all characters would be a
bit too much (especially the regex ones). But, I'm getting too enticed with
{{AND}}, {{OR}}, {{(}} and {{)}} along with already supported {{-}} and {{*}}.
So, how about using lucene's esacaping followed (correctly unescaping {{(, ), -
and &}}... and also, removing lower-casing of {{AND}} and {{OR}}. I think with
such operators being supported in google, users are used to parens, AND and OR
type operators for text fields type search boxes (which, imo, with most
relevant use of contains clause... AEM's code using contains, imo, is
exploitation :)).

Chetan Mehrotra commented on OAK-3769:

Yes there are some benefits of exposing the broader syntax. But remember that
here you cannot specify the field (within fulltext phrase) as the field is
implicit as per the first parameter of contains call. So its somewhat limited.
Further per JCR spec only certain chars are allowed. Expecting the users to
handle escaping would not be good and its better to not leak the implementation
much. Boost has got into use, so has been allowed but extending that precendent
further we need to be careful. Oak supports the native query which can be used
by user if they want to rely on such implementation detail.
It would be preferable to go with a restrictive set and expose operators on a
case by case basis

Vikas Saurabh commented on OAK-3769:
[~chetanm], I think it's a little bit lenient that current code passes on the
text sent in jcr:contains (almost) as is to lucene query parser. Thus,
theoretically, we are allowing a full lucene query grammar in contains clause
which might not be intent of code making the query on oak.
This
[comment|https://issues.apache.org/jira/browse/OAK-2329?focusedCommentId=14239456&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14239456]
in OAK-2329 seems to suggest that having lucene grammar at hand is useful.
Although, it kind of ties the usage with underlying implementation (that lucene
or solr is being used to server contains clause). I mean I can see a useful
usage of contains clause with proximity search.
The trouble with this is of course with the implementation of caller code -
should the caller code assume presence of an underlying lucene/solr index and
hence escape the incoming text itself (sure, oak can expose utility methods to
do that).
My preference tends towards going all the way with supporting lucene syntax and
let caller code escape (and thereby assuming underlying lucene index). To do it
though, we'd want to let 'AND' and 'OR' remains upper-cased.
So, for this particular issue, I think AEM's code should escape the string
passed into contains clause explicitly to manage that search text doesn't
contain characters which might make query unparseable.
BTW, a bit of justification on why I'm biased towards supporting lucene grammar
is:
* in-built property index based full-text query is very non-rich
* slow wrt lucene
So, presence of lucene index would change result which I think is not
technically correct - but the richness it would allow, imo, out-weighs that
theoretical issue ('theoretical' because I can't imagine a serious deployment
without lucene index configured to answer queries with contains clause)

Hi Chetan/Team,
I have a customer who is facing the same error
(https://daycare.day.com/home/adobe/adobe_eu/wwfo/83254.html) when he tries to
search a keyword having '/' in it, whether in Assets or Siteadmin.
I replicated the issue, and it happens on any keyword that has a odd number of
'/', i.e. if there are 1 or 3, or 5 (so on) number of / in the keyword criteria.
if the number of / is even (2, 4, 6 so on), the error doesn't occur.
The issue is same as the one reported here already: "Issue with / as escape
character in OAK"
The error displayed is the same:

[patch|^OAK-3769-v1.patch] with testcase.
Currently Lucene considers [following chars as
special|https://github.com/apache/lucene-solr/blob/lucene_solr_4_7_1/lucene/queryparser/src/java/org/apache/lucene/queryparser/classic/QueryParserBase.java#L983-L995]
{code}
char c = s.charAt(i);
// These characters are part of the query syntax and must be escaped
if (c == '\\' || c == '+' || c == '-' || c == '!' || c == '(' || c == ')'
|| c == ':'
|| c == '^' || c == '[' || c == ']' || c == '\"' || c == '{' || c ==
'}' || c == '~'
|| c == '*' || c == '?' || c == '|' || c == '&' || c == '/') {
sb.append('\\');
}
{code}
In Oak escaping is done in
[rewriteQueryText|https://github.com/apache/jackrabbit-oak/blob/trunk/oak-lucene/src/main/java/org/apache/jackrabbit/oak/plugins/index/lucene/LucenePropertyIndex.java#L1340]
method. It cannot directly use Lucene escape as some operator need to be
passed as is. The list of operators I know are [1]
{noformat}
- - [1]
+ - [1]
^ - For boosting query time
{noformat}
Current case is broken for '/' which I believe was made special char in Lucene
4.x as regex based searches are supported now. So not sure we just add '/' to
our escape logic or should be include other chars also
[~teofili] [~catholicon] Thoughts?
[~mreutegg] [~alexparvulescu] From JR2 experience any thoughts on what should
we do here.
