How to hide the (-) sign from facet filter block? I am displaying faceted blocks and current search block on the search page.

When I select a filter from any faceted block, it appears in the current search block and also in that faceted block with this sign (-). 

When I click on this sign it removes the filter from the search.

It is fine in current search block. But It should not appear in the faceted block.

Suppose If I select category1 from the facet block. In the current search block and in its facet block it appears like this (-) category1.

And I want that in the current search block it should appear like (-) category1 and in its facet block it should on display its name like category1 without the (-) sign.

Any one who know how to hide this in the facet block?
There are a couple of theme functions you can use to work with the display of these filters.

theme_facetapi_deactivate_widget($variables)

theme_facetapi_link_active($variables)

In your case, you could place the following in your theme's template.php file to edit the display of the deactivation 'button' of your facet:

function THEME_facetapi_deactivate_widget($variables) {
  return '';
}
