Template page

I have custom template pages and search form.

<div class=”search-box”>
<form method=”get” id=”searchform” action=”<?php echo esc_url( home_url( ‘/’ ) ); ?>” role=”search”>
<label for=”s” class=”assistive-text”><?php _e( ”, ‘lepenskivir’ ); ?></label>
<input type=”text” class=”field” name=”s” value=”<?php echo esc_attr( get_search_query() ); ?>” id=”s” placeholder=”<?php esc_attr_e( ‘pretra?i postove …’, ‘lepenskivir’ ); ?>” />
<input type=”submit” class=”submit” name=”submit” id=”searchsubmit” value=”<?php esc_attr_e( ‘Search’, ‘lepenskivir’ ); ?>” />
</form>
</div>

This form finds everything in posts, titles in pages but not the content.
How can resolve this?
