If we choose ftcontains() or matches(), then I think we may keep contains()
as it is. And since we choose a function form, 'text' doesn't have to be a
reserved keyword. Then, at this stage, we don't need to change anything to
integrate the full-text search feature.
One remaining issue as Chen said
For full-text search, I like "ftcontains()" since it's very intuitive.
Syntax for advanced full-text features such as stop words, analyzers, and
languages need a separate discussion.

And as it turns out, we already have some infrastructure to translate a
constant record constructor expression into a record in

So supporting that wouldn’t be too painful.

Maybe we could come up with a function form - *ftcontains*(). Here, ft is
an abbreviation for full-text. This function replaces "contains text" in
XQuery spec. An example might be:
XQuery spec: where $o.titile contains text "hello"
AQL: where ftcontains($o.title, "hello")

@Till: Got it. I agree to your opinion. The issue here for the full-text
search is that many function parameters that controls the behavior of
full-text search will be added in the future. Maybe this is not the issue?

Hi,
I think that our challenge here is, that XQuery is very liberal in the
introduction of new keywords, as the grammar is keyword free. However,
they
often use combinations of words "contain" "text" to disambiguate.
AQL on the other had is not keyword free and so each time we introduce a

All right, thanks!

All right, if the AQL surface doesn't lead to special tweaks in the
compiler, e.g., rewriting rules, the same infrastructure can be used for
SQL++.
I'm OK with the AQL function name change from contains() to
string-contains(), however you'll need map "contains" to "string-contains"
in FunctionMapU

@Yingyi: Yes. It's just a syntactic sugar - it can be anything:
"contains_text", "contains text" or "containstext". It would be nice if
one form of function is used for both AQL and SQL++. Currently, to follow
the Xquery spec, this doesn't work.

I just talked to Mike to resolve 'text' and he suggested an idea to check

There are many test cases that use *text* as one of its field name. We can
correct it using 'text' or `text`. But, if a user currently uses *text* as
its a field name of a dataset, then, clearly, yes, it will not work.

Making "text" a reserved word seems like a more breaking change than the

Reminder:
Related to the full-text search, a string function named *contains*() will
be renamed to *string-contains*() soon. Also, "*text*" will become a
reserved word just like "for" or "where". It will happen soon as the first
step to the full-text search merge. Here are more details about this
