the problem is like the topic. I'm not sure if I misunderstood something or I missed some configurations. The ES works fine in usual situations, but doesn't work with rexster gremlin extension. In java, I configured the graph as follows: [https://lh3.googleusercontent.com/-kd6vKDQdH6g/U7RbYPE-ciI/AAAAAAAAAHk/sSU5e5R3DMM/s1600/1.PNG](https://lh3.googleusercontent.com/-kd6vKDQdH6g/U7RbYPE-ciI/AAAAAAAAAHk/sSU5e5R3DMM/s1600/1.PNG) [https://lh3.googleusercontent.com/-9HiEPJmS1FQ/U7Rbjmg4oCI/AAAAAAAAAHs/2FgdAtjiBHc/s1600/2.PNG](https://lh3.googleusercontent.com/-9HiEPJmS1FQ/U7Rbjmg4oCI/AAAAAAAAAHs/2FgdAtjiBHc/s1600/2.PNG) In the extension, I wrote: \*String query = "v." + propKey + ": (" + propValue + ")"; \* _if(((TitanGraph) graph).indexQuery("search", query).vertices().iterator().hasNext()){...}_ When I invoked the extension, the rexster told: null pointer exception, unknown index, etc. As follows: [https://lh4.googleusercontent.com/-I0w-hVgu0F0/U7RdQCcjOZI/AAAAAAAAAH4/4l13192eR2k/s1600/3.PNG](https://lh4.googleusercontent.com/-I0w-hVgu0F0/U7RdQCcjOZI/AAAAAAAAAH4/4l13192eR2k/s1600/3.PNG) [https://lh3.googleusercontent.com/-phHCRqzQN6I/U7RdUkyE8oI/AAAAAAAAAIA/rhkTlffd8lI/s1600/4.PNG](https://lh3.googleusercontent.com/-phHCRqzQN6I/U7RdUkyE8oI/AAAAAAAAAIA/rhkTlffd8lI/s1600/4.PNG) After this, I searched some advices from google and made some configurations in rexster.xml [https://lh4.googleusercontent.com/-\_6zRCaQtvRw/U7ReJ41k4jI/AAAAAAAAAIQ/Nwgon5WqPtU/s1600/6.PNG](https://lh4.googleusercontent.com/-_6zRCaQtvRw/U7ReJ41k4jI/AAAAAAAAAIQ/Nwgon5WqPtU/s1600/6.PNG) Then, the problems seemed as another way. (As you can see, first\_example is the name of the graph.) [https://lh5.googleusercontent.com/-r8TvH5CxjqA/U7Rfb9NFNEI/AAAAAAAAAIs/epemSCk5-8c/s1600/8.PNG](https://lh5.googleusercontent.com/-r8TvH5CxjqA/U7Rfb9NFNEI/AAAAAAAAAIs/epemSCk5-8c/s1600/8.PNG) Besides, when I invoked the extension, I've been told: the graph is non-configured. [https://lh4.googleusercontent.com/-uPWbHmgKL28/U7RfO3PoVlI/AAAAAAAAAIk/6ndP888fGYA/s1600/7.PNG](https://lh4.googleusercontent.com/-uPWbHmgKL28/U7RfO3PoVlI/AAAAAAAAAIk/6ndP888fGYA/s1600/7.PNG) I've also tried the embedded mode. The problems seem to be the same. Plus, I'm using: Titan 0.4.2 Tinkerpop 0.2.4 Cassandra 2.0.7 ElasticSearch 1.2.1 This problem's driving me crazy. Any pointer would be appreciated!
