Some issues about querying.

[Alex K]

Is it possible to query by regexp? Example:

"fruits/apple/1" "is_in" "boxes/1"
"fruits/apple/2" "is_in" "boxes/2"
"fruits/apple/3" "is_in" "boxes/3"
"fruits/limon/3" "is_in" "boxes/1"
"bob" "took" "fruits/apple/2"

How can i query all apples or all fruits except taken by Bob? Is there something like "fruits/*" glob or regexp? Or may be I need to remodel set?

You may just change a model a bit:

"apple/1" "is_in" "boxes/1"
"apple/2" "is_in" "boxes/2"
"apple/3" "is_in" "boxes/3"
"apple/1" "is" "fruit"
"apple/2" "is" "fruit"
"apple/3" "is" "fruit"

And then query for g.V("bob").Out("took").Has("is","fruit")

Thank you! This is very interesting db. Sadly that is frozen.

This should work:

g.V("bob").Out("took").Except(g.V().Has("is","fruit"))

One moment. How to set logical nefation?

g.V("bob").Out("took").HasNOT("is","fruit")

Not frozen, it was only resting.  Expect to see lots of movement in the coming weeks.  One of my personal projects regarding it is full text search!
