Currently, you need to know the ID of the vertex when querying the ServiceColum.
ex) Movie(id: 1)
Add search function to allows you to perform queries even if you do not know the Vertex ID.
ex) Movie(search: "title has 'star wars'")
Also, since the amount of search may be large in this case, the functions provided by the Label also provide functions such as `offset/limit`.
Assuming that the following ServiceColumn is defined
'=': If the value of the property matches the supplied string
'contains': The value of the property contains the supplied string.
