	★US調査では、US分類がIPCよりヒットが多くなりますので、US分類の追加が望ましい。
	★IPCは、US基本形式のC09D011/00とEP基本形式のC09D11/00の両方を入れる。
		・USでも、基本のC09D011/00と記載した文献だけでなく、
		一般的なC09D11/00と記載した両方の記載がある。
		両方を検索式に入れなければヒットからもれる。（USPTOでも同様）
		・一方、EP検索では、C09D011/00はヒットがゼロ件、必ずC09D11/00と入力する必要がある。
	Syntax Examples
		Query	Description
		cat	Find all documents containing the word 'cat' in any field.
		ABST/cat	Find all documents containing the word 'cat' in only the abstract. (‘ABST’ can be replaced with the abbreviation for any text field)
		cat AND dog	Find all documents containing both the word 'cat' and the word 'dog'. The two words may be in different fields.
		ABST/cat AND dog	Find all documents containing the word 'cat' in the abstract, and the word 'dog' in any field.
		TTL/cat NOT dog	Find all documents containing the word 'cat' in the title, but do not include any documents which have the word 'dog' in any field.
		(cat OR dog) AND (leash OR fence)	Find all documents that contain either the word 'cat' or the word 'dog', and which also contain either the word 'leash' or the word 'fence.' Note that without the parenthesis this query would be interpreted in an entirely different manner due to binding order of AND versus OR. Parenthesis are very helpful in making sure your query mean what you intend.
		APD/12/14/2000	Find documents with only this specific application date. (‘APD’ can be replaced with any date field)
		APD/12/14/2000 ->12/31/2005	Find all documents with an application date between the first date and the second date, inclusive.
		APD/12/14/2000 ->NOW	‘NOW’ is a convenient way to specify “today” in dates. Note that in Alerts and Saved Searches, ‘NOW’ automatically takes on the meaning the current day.
		[with word stemming on] electroplate	Find all forms of the word 'electroplate', including 'electroplated', 'electroplating', and 'electroplater'. Word stemming is based on language rules and may not find all forms of all words (to be more inclusive, use wildcards).
		“cat dog”	Phrase query. Find the phrase “cat dog” with no intervening words, in that order. Wildcards are not allowed (e.g., “cat do*”).
		"cat dog"~5	Proximity query. Find all documents containing the word 'cat' within 5 words of 'dog'. The 5 may be replaced with any whole number.
		cat^5 OR dog	Search term weighting. ‘Cat’ is 5 times more important to the relevancy of matching documents than ‘dog’. Find all documents containing the word 'cat' or 'dog' but, all other things being equal, rank the documents containing cat higher. The "5" may be replaced with any whole number.
		cat*	Unlimited Character Wildcard. Find documents containing words starting with ‘cat’ like cats, cathode, category, etc. Useful when you need to be more inclusive than word stemming allows.
		do?	Single-character Wildcard. Find all documents containing words that has only one character after 'do' like doe, dog, dot, etc.
