setup `songhay-index-day-path-blog` repo

[BryanWilhite]

this issue will explore the first time use of https://www.npmjs.com/package/@songhay/index applied to Day Path Blog

• will lunr be of use here and will need to become a dependency in @songhay/index?
• will Bing Web Search work out here?

[BryanWilhite]

today it looks like @songhay/index should be installed directly into the static web site repo (#11)

additionally, after working intensely with Bing search I see that

• Bing search scoped to site: does not guarantee finding a document that you know is there (and should be indexed by Microsoft)
• search keywords for a document (even when specified in quotes) may not return the document when some of search terms trigger an ‘override’

so when your document title contains brittany spears, canned search results will be returned for the celebrity name—no matter how explicit your search for your document is

bottom line: i now see that lunr will give me 100% control over my search experience and i must rely on my index-building talents, forgoing third parties
