To match nodes or edges based on a value within a set or list property in
HugeGraph, you need to use the `CONTAINS` or `TEXT_CONTAINS` operators. These
operators are specifically designed for querying properties with cardinality of
`SET` or `LIST`. Here's how you can use them in your Gremlin query:
1. **Ensure Search Index is Configured**: First, make sure that a Search
index is configured for the `alias` property. This is necessary for using
full-text search capabilities like `CONTAINS` or `TEXT_CONTAINS`.
2. **Use the Correct Query Syntax**: Modify your Gremlin query to use the
`CONTAINS` operator. For example, to find vertices where the `alias` property
contains a specific value, you can use:
```java
g.V().hasLabel("org").has("alias", CONTAINS, "广州软件").limit(10)
```
Alternatively, if you want to use `TEXT_CONTAINS`, the syntax would be:
```java
g.V().hasLabel("org").has("alias", TEXT_CONTAINS, "广州软件").limit(10)
```
These operators will allow you to match vertices based on the presence of a
specific value within the `alias` set property. Ensure that the index type for
`alias` supports these operations, as secondary indices are typically used for
such queries
