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.
