2.1 For a phrase search, the snippet should start from the beginning of a sentence which contains the query; This means the query itself may not appear in the snippet: this is possible when a sentence contains the query, but that query does not appear in the first 120 characters of the sentence.
2.1 For a phrase search, the snippet should start from the beginning of a sentence which contains the query; This means the query itself may not appear in the snippet: this is possible when a sentence contains the query, but that query does not appear in the first 120 characters of the sentence. If the query appears multiple times in a document, consider the first occurrence only. In other words, to construct the snippet, your program should search the first occurrence of the query in the document.
2.2 For a regular search, if an exact match can be found in the document, the snippet should start from the beginning of a sentence which contains the query; if an excat match can not be found, the snippet should start from the beginning of a sentence which contains the first keyword of the query, and the first occurrence of this first keyword within the document is in this sentence.

**Note**, to simplify the construction of the snippets, we have tailored the provided HTML files such that you can identify the beginning of a sentence via searching the period sign before the sentence. In this assignment, you can assume that there is always a period sign before the sentence which contains the snippet you are going to construct, however, it is possible that there exist some white spaces in between the period and the start of the sentence.
