Phrase Search

Phrase search is used to precisely match the target phrase. For example, the search statement abc def matches all logs that contain both abc and def regardless of the sequence. For details about the differences between phrase search and keyword search, see Table 1.

• Phrase search: It is implemented based on the keyword search syntax. Phrase search can distinguish the sequence of keywords and is used to accurately match target phrases, making the search result more accurate. Phrase search is applicable to English phrases and Chinese phrases, but cannot be used together with fuzzy search.
• Keyword search: Keyword search is implemented based on word segmentation. Delimiters are used to split the search content into multiple keywords for log matching. Keyword search does not distinguish the sequence of keywords. Therefore, as long as a keyword can be matched in a log based on the AND or NOT logic, the log can be found.

  Table 1 Differences between two search modes

  Search Mode	Phrase Search	Keyword Search
  Differences	Distinguishes the sequence of keywords and is used to accurately match target phrases, making the search result more accurate.	Does not distinguish the sequence of keywords. The keyword is matched based on the search logic.
  Examples	Assume that your log stream contains the following two raw logs: Raw log 1: this service is lts Raw log 2: lts is service
  	If you search for the phrase #"is lts", one log is matched.	If you search for the keyword is lts, two logs are matched.
  	If you search for the phrase #"lts is", one log is matched.	If you search for the keyword lts is, two logs are matched.
