Search using Apache TinkerPop methods on strings
Using Apache TinkerPop predicates with DSE Search indexes
Apache TinkerPop predicates can be used with DSE Search indexes in DataStax Graph (DSG).
Note that this kind of search on strings is case-sensitive, so using Pork
or pork
will find different results.
The supported predicates are:
-
containing()
-
notContaining()
-
startingWith()
-
notStartingWith()
-
endingWith()
-
notEndingWith()
containing()
In a traversal query, use a string search to list all recipes that have the word Pork
in the recipe name.
A partial match of the recipe name returns a result, unlike eq()
.
Note that this search is case-sensitive, so using pork
would not find a vertex.
g.V().has('recipe', 'name', containing('Pork')).values('name')
results in:
==>Roast Pork Loin
notContaining()
In a traversal query, use a string search to list all recipes that do not have the word Pork
in the recipe name using notContaining()
.
A partial match of the recipe name will exclude the name from the result, unlike neq()
.
g.V().has('recipe', 'name', notContaining('Pork')).values('name')
results in:
==>Salade Nicoise
==>Wild Mushroom Stroganoff
==>Spicy Meatloaf
==>Oysters Rockefeller
==>Rataouille
==>Carrot Soup
==>Beef Bourguignon
startingWith()
In a traversal query, use a string search to find all recipes that have a name beginning with Beef
.
The method startingWith()
is used with a supplied string.
g.V().has('recipe', 'name', startingWith('Beef')).values('name')
results in:
==>Beef Bourguignon
Matches are found for each recipe name that begins with Beef
, provided the recipe name was designated with asString()
in the search index.
A search using startingWith('Bee')
will find the same result;
full words are not necessary.
|
notStartingWith()
In a traversal query, use a string search to find all recipes that do not have a name beginning with Beef
.
The method notStartingWith()
is used with a supplied string.
g.V().has('recipe', 'name', notStartingWith('Beef')).values('name')
results in:
==>Salade Nicoise
==>Wild Mushroom Stroganoff
==>Spicy Meatloaf
==>Oysters Rockefeller
==>Rataouille
==>Carrot Soup
==>Roast Pork Loin
endingWith()
In a traversal query, use a string search to find all recipes that have a name that ends with Soup
.
The method endingWith()
is used with a supplied string.
A search using endingWith('oup')
will find the same result;
full words are not necessary.
g.V().has('recipe', 'name', endingWith('Soup')).values('name')
results in:
==>Carrot Soup
notEndingWith()
In a traversal query, use a string search to find all recipes that do not have a name that ends with Soup
.
The method notEndingWith()
is used with a supplied string.
g.V().has('recipe', 'name', notEndingWith('Soup')).values('name')
results in:
==>Salade Nicoise
==>Wild Mushroom Stroganoff
==>Spicy Meatloaf
==>Oysters Rockefeller
==>Rataouille
==>Beef Bourguignon
==>Roast Pork Loin
