How to extract portions of an event?

[kkompalli]

I have a event which is like below.

"searchString" index=ABC1............XYZ1"/searchString" 123456789 "searchString"index=ABC2.....................XYZ2"/searchString" 

I want to extract the data between "searchString" and "/searchString" .
the output should be like below

index=ABC1............XYZ1
index=ABC2.....................XYZ2

In you SPL, you could try this

.... | rex "searchString"\s(?<ss>[^"]*)"\/" | ...
