Since CPS Path  has support of and, or, multiple and's, multiple or's . It supports and/or also but the result is not as expected since leaf elements are stored in map the order of map is not preserved which impacts the expected result.

For examples we have

cps-path : //books[@title="Good Omens" or @price=15 and @edition=1983]

                 //books[@numberOfBooks=1 and @title=matilda or @price=150]

The outcome of query is  is completely differ from given cps-path

Query formed : SELECT * FROM FRAGMENT WHERE anchor_id = :anchorId AND xpath ~ :xpathRegex AND ( attributes @> '{"price":15}' or  attributes @> '{"edition":1983}' and  attributes @> '{"title":"Good Omens"}' 

Expected query: SELECT * FROM FRAGMENT WHERE anchor_id = :anchorId AND xpath ~ :xpathRegex AND ( attributes @> '{"title":"Good Omens"{color}}' or  attributes @> '{"price":15}' and  attributes @> '{"edition":1983}'
