how to change backslash of text input of a dashboard to use in subsequent search?

[zakir_hussain]

the value of the backslash \ to double backslash \\ in side of token is sets up in dashboard xml.
tried following but did not worked.
<eval token="input_tok">replace($form.input_tok$, "(\\\\)", "\\\\\1") </eval>

opps, it did work, my eval was not written correctly, i think, i was missing  space after commas in below syntax.

<eval token="input_tok">replace($form.input_tok$, "(\\\\)", "\\\\\1")
