[PerlChina] Re: A hash which contains additional optional highlighting parameters 这个哈希结构该如何创建?

$opts = {
  before_match => "<b>",
  after_match => "</b>"
}

效果为 <b>keywords</b>

reference to hash 是一种可选参数的传递方式。

函数为 $excerpts = $sph->BuildExcerpts($docs, $index, $words, $opts)

opts项的说明为:
opts
A hash which contains additional optional highlighting parameters:

before_match - a string to insert before a set of matching words,
default is "<b>"
after_match - a string to insert after a set of matching words,
default is "<b>"

如何预定义这个别opts结构呢?

函数来自于Sphinx::Search模块
