💖 XSEARCH(1) 💖

✨ NAME ✨

xsearch — search an indexed local NCBI Entrez Direct archive. that's the whole vibe. 🎀

🌸 SYNOPSIS 🌸

xsearch [-h[elp]|[--]help] -query|-match|-exact|-title|-words|-pairs
query...

like. she's a little dense but she's perfect. look at her go 💅

🫶 DESCRIPTION 🫶

okay so here's the tea: xsearch searches an indexed local NCBI PubMed archive — the kind of thing that gets prepared by archive-pubmed(1) or something similar. that's literally the job. no notes. periodt. ✨

👑 OPTIONS 👑

pick your fighter bestie, every single one is valid:

• -query — search on words or phrases, but make it Boolean formulas. the whole little logic situation. 🔥
• -match — ranked partial term matching. she's matching terms partially, and she's ranking them. slay.
• -exact — strict search for article round-tripping. strict!! no fudging, no improvising. 💀
• -title — exact search, but limited to the indexed title field. just the title, bestie. nothing but the title. 🎀
• -words — combine searches for individual informative words. one word at a time, like a queen.
• -pairs — combine searches for pairs of adjacent informative words. two words, sitting next to each other, being searched together. cute. 🦋
• query... — what to actually search for. may contain standard Boolean operators AND, OR, and NOT, and yes you can use parentheses as needed for grouping. use them. group responsibly. 🌸
• -h[elp]|[--]help — print a summary of options and some usage examples. the tutorial level. the little guided tour. take it. 💜

🌈 ENVIRONMENT 🌈

• EDIRECT_LOCAL_ARCHIVE — the local archive directory to use. it's expected to hold an absolute path, so like, no shortcuts, no relative chaos. give her the full path bestie. 👑
