searching for tab key usage with shift modifier, searched for keytab using ag/rg/ack and nothing useful try using cs and its right at the top

1. The runaway goroutines
2. the highlight snippet issue
3. a help for tui like tig???
4. filter on filename
5. ignore minified/generated files
6. display the number of processed files
7. be able to look though the results using keys

Look into using the below to read PDF, DOC, DOCX, XML, HTML, RTF, into plain text for searching https://github.com/sajari/docconv

package main

import ( "fmt" "log"

 "code.sajari.com/docconv"

)

func main() { res, err := docconv.ConvertPath("your-file.pdf") if err != nil { log.Fatal(err) } fmt.Println(res) }

https://www.researchgate.net/publication/4004411_Topic_extraction_from_news_archive_using_TFPDF_algorithm

A number of term-weighting schemes have derived from tf–idf. One of them is TF–PDF (Term Frequency * Proportional Document Frequency).[14] TF–PDF was introduced in 2001 in the context of identifying emerging topics in the media. The PDF component measures the difference of how often a term occurs in different domains. Another derivate is TF–IDuF. In TF–IDuF,[15] idf is not calculated based on the document corpus that is to be searched or recommended. Instead, idf is calculated on users' personal document collections. The authors report that TF–IDuF was equally effective as tf–idf but could also be applied in situations when, e.g., a user modeling system has no access to a global document corpus.

Ill be blowed. I wrote this years ago https://boyter.org/2013/04/building-a-search-result-extract-generator-in-php/ based on an even older stackoverflow answer. Turns out it was picked up by a bunch of PHP projects https://github.com/msaari/relevanssi/blob/master/lib/excerpts-highlights.php https://github.com/bolt/bolt/blob/master/src/Helpers/Excerpt.php and https://github.com/Flowpack/Flowpack.SimpleSearch/blob/master/Classes/Search/MysqlQueryBuilder.php Whats interesting to me is that Relevanssi is the wordpress plugin that improves your search results and has 100,000+ installs. Which probably means the most successful code in terms of spread and use is in PHP and I have NEVER been paid to write PHP ever in my life.

Mostly about ranking/highlighting snippet extraction links
