Placeholder in #quick-search-query

[Vignesh Suri]

I want a customized placeholder in #quick-search-query How can I do that? Current confluence version is 5.10

By default, when I inspect the #quick-search-query, I see this: 

<input id="quick-search-query" class="text app-search search quick-search-query" accesskey="q" autocomplete="off" name="queryString" title="Quick Search (/or g , g)" placeholder="Search" type="text">

But the "Search" placeholder does not appear. Why? Moreover I need to customize this. How can I do it?

You could write an own macro where you define the placeholders as parameters and within this plugin you call the quick-search-query inserting your placeholders.

I did something similar on this question for a different macro. (The last answer)

You could adapt from that
