For functions related to Internet Archive

Notes:

1. Internet Archive runs Elasticsearch search engine as of 4 Nov 2015

2. Program flowchart:

Break name down into number of words Build a base URL based on number of words (1,2,3,4,5+), use of sopt=t switch, and availability of birth-death dates If any words contain extended-ascii characters append extra code for wildcards based on sopt=t or w           return finished URL

3. URL length should not exceed 2000 characters or it will break certain popular browsers

4. Wildcard (*) replacements should be avoided in the first letter of the first word, and with any single-letter words 5. Changing search formulations will have impacts on existing uses of the template and off-line tools which are optimized for these search recipes. ]]
