Having upgraded to 9.0.1FP4SR1, it seems as if parentheses no longer work in web search queries.
For example, it used to be possible to use a query like
(FIELD Foo = "value1" AND FIELD Bar = "value2") OR (FIELD Baz = "value3")
Or even just
(FIELD Foo = "value1")
For example, /mydb.nsf/View?SearchView&query=(FIELD%20Foo%20=%20"Bar")
Now, queries with parentheses give me an error saying the query is not understandable, or fail to return results correctly. They're fine in the Notes client, however.
Is anyone else seeing this?
