Autocomplete with RESTXQ
by Imsieke, Gerrit, le-tex 21 Jul '21

21 Jul '21

Hi List, Can anyone recommend a lightweight vanilla Javascript autocomplete library that can easily be used together with BaseX RESTXQ? Maybe even a readily cloneable/modifiable example? I don’t have a preference for a server response format. The RESTXQ service may be configured to return XML, JSON, or HTML No CORS restrictions need to be considered, the query host is the same that delivers the HTML pages. Gerrit

Package for system integration
by karlo＠fastmail.com 20 Jun '21

20 Jun '21

I have packaged basex in a way that I believe will be easier for integration with package managers. https://klarinet.kos.ovh/fossil/basex-root-install/uv/basex-9.4.3.tar.gz >From the root of that archive, you can build and install like this. make make install # as root The above will install to the prefix /usr/local. You can set a different prefix. Here is an example. make clean make PREFIX=/usr make PREFIX=/usr install # as root A secondary benefit of this package is the removal of the bash dependency. Could a package like this be distributed officially? If that is agreeable, I am happy to try incorporating this into the present build system. Here is a utility for preparing the package. It depends on sh and other Unix-like utilities. https://klarinet.kos.ovh/fossil/basex-root-install/dir?ci=tip With distinguished salutations, Kralj Karlo

Options for ft:search
by Sebastian Zimmer 15 Mar '21

15 Mar '21

Hi, I'd like to request a feature concerning the ft:search method: An `lserror` option that works exactly like the global option `LSERROR`. It would be nice if we could set the maximum Levenshtein distance specifically for each fuzzy search without having to adjust the global option. Another question on ft:search: Is there a reason why it doesn't have a `case` option just like ft:contains has one? Best regards, Sebastian

king Henry VIII dalenda est
by Liam R. E. Quin 05 Oct '20

05 Oct '20

At https://words.fromoldbooks.org/Search/ a search for henry shows lots of matches, and sodoes a search for henry i, but henry ii and henry viis missing and so is henry viii. I can search for viii and find Henry VIII and also Charles VIII, but i also can't search for Charles VIII. I can search for the king’s feet, and for Henry V, but not Charles II. It looks like words ending in ii are invisible. I'm using ft:search("wobo", $term)/ancestor-or-self::p Might this be related to stemming? i have that turned off This is used to create the db (from the Perl API) # create query instance t("drop db wobo"); t("create db wobo"); t("open wobo"); $session->send("set chop false"); $session->send("set ftindex true"); $session->send("set updindex true"); $session->send("set autooptimize true"); txf("/home/liam/w/Search/wobo.xml"); t("create index attribute"); t("create index text"); t("create index fulltext"); t("optimize"); t("close"); t("quit"); where t() just does a $session->execute() on its argument after printing a trace line, and txf does a delete followed by an add. Probably i can make a test case available if needed.

Mapping query-params to $options argement of ft:functionj
by Günter Dunz-Wolff 05 Oct '20

05 Oct '20

Hi all, is there a possibility to match the query-parameters more directly to the $options argument of a ft:function? In the moment I have a rather complicated if-else-if-else-if…-scenario. Example: if ($wildcards = "on" and $all = "on" and $case_sensitive = "on" and $using_diacritics = "on") then $collection[.//text() contains text {$query} all words using case sensitive using diacritics sensitive using wildcards] else if and so on. Depending on query-params I want to build the ft:function with $options argument more directly. (But for example string-concatenation doesn’t work.) Thanks for any advice. Guenter

Thanks Gerrit, invoking search and passing all params per GET is the way to go.

Paging results of an XQuery-Search
by Günter Dunz-Wolff 26 Sep '20

26 Sep '20

Hi all, is it possible to present the results of an XQuery search in parts of 50? In order to speed up the search, only the first 50 results should be displayed and only if the user is interested in further results, 50 new results each should be displayed. Is this even possible? I did not find anything about it in the documentation. Example: let $collection := collection("data") let $hits := $collection//*:s[.//text() contains text {$query_string}] let $count_hits := count($hits) return <div> { if $count_hits <= 50 then <ol> {for $hit in $hits return <li>{$hit}</li> </ol> else ??? } </div> Thanks for any advice. Best regards Guenter
