Search tips

As these web pages include one document each (either letter, essay, press item, or editorial priliminars) together with the editorial notes, the search engine

  1. will not combine searches across documents, but only within each document
  2. will pick up not only Harrod's own words, or his correspondents', but also what appears in the annotations.

By default the search engine tries to locate pages which have exact matches for all of the words entered in your search query. If that fails, it then tries to locate pages which contain any words in your search query. If that happens a short message is displayed at the top of the search results indicating this has been done.

In addition, there are several ways to modify the default search behavior.

 1. phrase search

The search engine supports three types of phrase search.
  • To match an exact phrase, use quotes around the phrase
    • Example: "capital-output ratio"
  • To match a near (within a couple of words) phrase, use square brackets [around the words]
    • Example: [capital output]
  • To match a far (within several words) phrase, use braces { around the words }
    • Example: {capital output}

2. + and - qualifiers

  • If you prepend a word with + that word is required to be on the page.
  • If you prepend a word with - that word is required to not be on the page.
    • Example: +kahn -keynes

3. * wildcard

  • If a query word ends with a * all words on a page which start the same way as that query word will match.
    • Example: keynes*

4. ? wildcard

  • If a query word contains a ? any character will match that position.
    • Example: b?g

5. boolean search

  • You can use the following boolean operators in your search: AND, OR, NOT. These operators MUST be in capital letters.
    • Example: (kahn AND robinson) OR (durbin AND meade)

6. All of these techniques can be combined

Example: +alway* -ne??r*
