Search the Food Irradiation 2 Wholesomeness Collection
To search, simply enter a query -- type the words you want to search for in the 'search term box' (or follow the instructions from your client as to how to enter a search). If you enter two or more words, then any document that contains ANY of the words will be found. (For example, if you search for cereal grains, then any document with either cereal or grains will be on the list.) If you want only documents containing BOTH cereal AND grains, then use AND between the words; your query would be: cereal and grains. See the list below for a full description of searching options and their effect. The result of this search will be a list of the documents which satisfy your search request (or a reply that indicates that NO documents match). The list is ordered by 'relevancy rank' (highest first), which very roughly corresponds to the number of times the word you searched for occurred in the document versus the size of the document.
The following is a list of all the search options available:
- Right-hand truncation (stemming) queries -- Expand Your Search
- The query 'nutrition*' will find documents containing the words 'nutrition' as well as 'nutritionist'. If you are not sure of the
spelling or form of the word used in the documents, use this.
- 'And' queries -- Narrow Your Search
- The query 'red and blue' will find the intersection of all the documents containing the words 'red', and 'blue'.The use of 'and' limits your retrieval.
- 'Or' queries -- Expand Your Search
- The query 'red or blue' will find the union of all the documents containing the words 'red' and 'blue'.The use of 'or' increases your retrieval.
- 'Not' queries -- Narrow Your Search
- The query 'red not green' will find all the documents containing the word 'red', and excluding the documents containing the word 'green'.The use of 'not' limits your retrieval.
- Nested queries -- Complicated Searches
- The query '(red and green) or blue not pink' will find the union of all the documents containing the words 'red', and 'green'. It will then add (union) all documents containing the word 'blue'. Finally, it will exclude all documents containing the word 'pink'.
