3.13 在TinkerPop3.4中新加的搜索谓词 New text search predicates added in TinkerPop 3.4 实用的小精灵（Gremlin图查询语言） 阿岶奇TinkerPop向导 PRACTICAL GREMLIN An Apache TinkerPop Tutorial

在阿帕奇TinkerPop3.4版本，最让人期待的特性就是增加了新的谓词，它们有助于进行文本搜索。

Probably one of, if not the, most anticipated features in Apache TinkerPop version 3.4 was the

addition of new "predicates" that aid in performing more focused text searches.

文本谓词的更多信息可以从阿帕奇TinkerPop文档中找到。位置是http://tinkerpop.apache.org/docs/current/reference/#a-note-on-predicates

Additional information on the text predicates can be found in the official Apache

TinkerPop documentation here: http://tinkerpop.apache.org/docs/current/

reference/#a-note-on-predicates

总计6个新的谓词加到了小精灵查询语言中。其中三个是用于指示搜索在文本的字符串中存在一个或多个字符，三个是用于不存在一个或多个字符。

In total, six new predicates were added to the Gremlin query language. There are three predicates

that search for the existence of one or more characters within a string of text and three that search

for the non existence of one or more characters.

 在本节下面的内容中，您将会找到每个谓词使用的例子。每个谓词都是大小写敏感的，在使用它们的时候一定要记得。要做大小写敏感的检索，您可以把多个步骤用一个or步骤组合在一起。

In the sections below you will find examples of each predicate being used. Each predicate is case

sensitive so bear that in mind as you use them. To do a case insensitive search you can chain

multiple steps together combined by an or step.

所有这些谓词都是大小写敏感的。这现谓词加到已的的小精灵谓词中，我们可以在“测试值和值的范围”这一节中看到。

 All of these predicates are case sensitive.

These predicates add to the existing Gremlin predicates that we looked at in the Testing values and

ranges of values section.
