In
`@src/main/java/com/netgrif/application/engine/pfql/domain/antlr4/QueryLang.g4`:
- Line 374: Update the javaId parser rule in QueryLang.g4 to include the NULL
token as an alternative alongside JAVA_ID, allowing null to be used in property
paths such as data.null.value while preserving existing identifier parsing.
In
`@src/main/java/com/netgrif/application/engine/pfql/service/QueryLangEvaluator.java`:
- Line 1637: Update the Mongo null-check branches in QueryLangEvaluator to
target QPetriNet.petriNet.title.defaultValue for process and task title checks,
matching the other title comparisons and Elasticsearch behavior; leave the
QCase.case$.title branch unchanged because it is already a plain string path.
- Line 1748: The null-comparison listeners exitLaNull and exitLfNull currently
produce no predicate, causing lastAssign and lastFinish null expressions to
match every task; update them to reject these unsupported attributes explicitly
rather than silently continuing, consistent with the existing TODO handling for
lastAssign and lastFinish.
- Line 1854: Add a FUZZY entry to SearchUtils.comparisonOperators allowing only
EQ and NEQ, then validate both fuzzy listeners against it. In
QueryLangEvaluator.java lines 1854-1854, update exitTitleLike to call checkOp
with the fuzzy comparison type before buildElasticQuery; in lines 1877-1878,
update exitDataStringLike to use the same fuzzy type instead of
ComparisonType.STRING.
- Around line 1864-1865: Update exitTitleLike so the Mongo fuzzy predicate
applies the comparison operator consistently with the Elasticsearch path: negate
the likeIgnoreCase predicate when op is NEQ or the explicit not flag is set, and
otherwise retain the positive predicate. Reuse the existing op and not values
and pass the resulting predicate through setMongoQuery.
In
`@src/main/java/com/netgrif/application/engine/pfql/service/utils/SearchUtils.java`:
- Around line 187-191: Update getStringValue to return only the
apostrophe-stripped raw value without Elasticsearch quoting. Apply quoting
exclusively when constructing scalar Elasticsearch values, and quote each string
element individually before joining list predicates; preserve the surrounding
parenthesized list syntax.
In
`@src/main/java/com/netgrif/application/engine/workflow/web/WorkflowController.java`:
- Line 137: Update the PFQL search error handling in WorkflowController to avoid
logging e.getMessage(), since it may contain rejected external query input.
Replace it with a fixed, non-sensitive warning event or a properly sanitized
message while preserving the warning behavior.

- Around line 473-476: Update quoteForElastic so tilde characters within STRING
values remain part of the quoted value instead of being split into fuzzy
metadata; only extract fuzzy information when it is syntactically separate from
the string. Preserve fuzzy query handling while ensuring values such as “release
~ candidate” are emitted entirely as a literal string.
- Around line 466-479: The quoteForElastic path must not produce phrase-slop
syntax such as "value"~2 for multi-word fuzzy values. Update the callers or
query construction around exitTitleLike, exitDataStringLike, and
SearchUtils.buildElasticQuery so fuzziness is applied per term or through an
equivalent structured Elasticsearch query while preserving non-fuzzy phrase
handling, and add a regression test covering a multi-word value with ~2.

Java Pattern default \s Unicode whitespace UNICODE_CHARACTER_CLASS Java version documentation
💡 Result:
In Java, the behavior of the regex character class \s depends on whether the UNICODE_CHARACTER_CLASS flag is enabled. Default Behavior When the UNICODE_CHARACTER_CLASS flag is not set (which is the default), \s matches only US-ASCII whitespace characters: [ \t\n\x0B\f\r] [1][2][3]. Unicode-Aware Behavior When the UNICODE_CHARACTER_CLASS flag is enabled (via the Pattern.UNICODE_CHARACTER_CLASS constant or the embedded flag expression (?U)), the \s character class becomes Unicode-aware [4][5][6]. In this mode, it conforms to the recommendations of Unicode Technical Standard #18: Unicode Regular Expressions, Annex C: Compatibility Properties, matching a broader set of Unicode whitespace characters [4][5][6]. Language-Level Escape Sequence (\s) It is important to distinguish the regex character class \s from the Java language-level escape sequence \s. Since Java 15, \s is a valid string literal escape sequence that represents a space character (\u0020) [7]. Before Java 15, using \s in a string literal (e.g., "\s") would result in a compile-time error ("illegal escape character") because it was not a recognized escape sequence [7]. To use the regex \s in string literals for older Java versions, developers typically escape the backslash (e.g., "\s") to pass the literal string "\s" to the regex engine [7]. Documentation Official documentation for the Pattern class is available in the Java SE API specifications for all versions [1][2][3][4][5][6][8]. The behavior of \s and the impact of the UNICODE_CHARACTER_CLASS flag are explicitly documented under the Predefined character classes section of the Pattern class Javadoc [1][2][3].

Align whitespace detection with fuzzy-term splitting.
The project targets Java 11. containsWhitespace accepts U+2003, but resolvePhraseWithFuzzy uses default \\s+ without UNICODE_CHARACTER_CLASS. Therefore, foo\u2003bar~AUTO can produce one fuzzy term instead of (foo~AUTO AND bar~AUTO). Use \\p{javaWhitespace}+ or enable UNICODE_CHARACTER_CLASS.

In
`@src/main/java/com/netgrif/application/engine/pfql/service/utils/SearchUtils.java`
around lines 492 - 499, Update the whitespace splitting logic in
resolvePhraseWithFuzzy to use Java whitespace semantics consistent with
containsWhitespace, such as a javaWhitespace-based pattern or Unicode character
class. Ensure separators like U+2003 split fuzzy phrases into individual terms
while preserving existing ASCII whitespace behavior.
