在新手册中创建Credit Memo的API调用是什么？(What are the API Calls to create the Credit Memo in freshbooks?)

 我很确定突出显示查询字符串是不可能的 - 只突出显示索引中的部分文档。 
 
 您可能尝试的是将查询字符串本身索引在其自己的索引中，然后使用第一个查询的结果作为针对查询字符串的第二个查询的查询项（在第二个索引中）。 然后，您可以在查询字符串上突出显示。 你每次都要向ES发出额外的请求，但我认为它会得到你想要的。 

I'm quite sure highlighting the query string isn't possible - only highlighting parts of documents in an index. 
 
What you might try is indexing the query string itself in it's own index and then using the results of the first query as the query terms for a second query against the query string (in the second index). You could then have highlighting on the query string. You'll have to make an extra request to ES each time, but I think it'll get what you want.
