• Port of drivine4j#626: a pooled session that built a schema index in parallel keeps its shared memory, so a later vector index can't be built in a 64 MB /dev/shm

• Full-text search reads a query's words with \W where the text's expression reads Alphabetic and decimal digits: a Hindi word never matches, ² stays in a word

• Cypher on SQL stores: a list or map parameter as a list index, or a list parameter indexed by a text, a truth value or a float, gives null or an item where Neo4j refuses it
