Phrase matching for keyword matching patterns
Baidu did not split the phrase matching in the early stage, and continued to improve it in the later stage to expand the phrase matching mode to exact inclusion, synonymous inclusion, and core inclusion, in order to allow promotion users to have more mode choices for their own industry promotion.
Exact inclusion
Exact inclusion means that when a netizen's search term fully contains a keyword, the system can display the promotion results. Its coverage is slightly wider than the exact match, for example, the keyword in the account is "34567", after setting it to exact inclusion, netizens can trigger keywords such as "1234567" and "3456789".
With exact inclusion, the search term contains the keyword exactly, but the keyword itself cannot be split. For example, if the account keyword is "34567", after setting the exact inclusion, netizens search for "3456789".

Synonymous contains
Synonymous inclusion means that when netizens' search terms have similar meanings to keywords, are inverted compared to keywords, and insert text into keywords, users' promotional information still has the opportunity to be displayed. For example, if the keyword in the account is "34567", after setting synonym inclusion, the search terms that can trigger the user's keyword are as follows: synonymous inclusion
Similar meanings (search terms): 345 six seven, 34 Wu six seven, three four 567.
Position reversal (search terms): 67-345, 567-34.
Insert (search terms): 34-12-567, 34-89-567, 3456-89-7
and similar meanings and position reversed, inserted: 12-345, 12-3456, 67-12345.
Synonyms include that when netizens' search terms have similar meanings to keywords, are inverted compared to words, and insert text into words, promotional information still has the opportunity to be displayed
Since the search terms corresponding to the keywords included in the setting synonym also maintain a high degree of relevance, and the coverage is neither too narrow nor too wide, so the synonymous inclusion is the most commonly used matching mode in enterprise promotion.
Core contains
Core inclusion is also known as "de-redundancy inclusion" "de-redundancy" means "removing superfluous", when the netizens' search terms contain the core part of the triggered keyword, the user's promotion information has the opportunity to show. For example, the word is "34-56-7", after setting the core inclusion, the system thinks that "34 or 56" is the keyword, so when netizens search for "12-34", "56-789", "12-34-89". Keywords may be triggered, i.e. those that contain core words may appear.
Core inclusion means that the core word may be displayed
