Re: [EP-tech] EPrints Search - Latest Items

Thanks for sharing, I'm sure most of us will will appreciate it. A generic latest-like page with a search.pl search entry and some parameters could be useful in a lot of situations.

Also reusing the advanced search can help:

https://livrepository.liverpool.ac.uk/cgi/search/archive/advanced?title_merge=ANY&title=covid+coronavirus

but it does AND by default if you add the keyword, so if you add the keyword you get only 1 result:

https://livrepository.liverpool.ac.uk/cgi/search/archive/advanced?title_merge=ANY&title=covid+coronavirus&&keywords_merge=ANY&keywords=covid+coronavirus+covid19

So adding a way to add an "or" search in search.pl search entries could help.

Hi Yuri,

Thank you for that. I had looked at the wiki page for this previously, but I'd not registered the add_field part. I was trying to add fiels/terms to the structure in the latest_tool.pl file that sets up the filters.

The part I addedlooks a bit like this, with some other parts that made it work too.

I'm 99% sure most on this list could do this task quicker and better than I have, but tomorrow I'll share the various bits of code and where to put them if anybody is interested. 

This is the results page for it:


I've also put a box on the repo home page which updates on refresh (again, exactly how the latest_tool works just with a different search query and page title etc.). 

Thanks again for the pointers, I really appreciate it.

James

The part I added looks a bit like this, with some other parts that made it work too:

$searchexp->add_field(
fields => [
      $ds->field( "title" ),
    ],
    value => "coronavirus",
);
$searchexp->add_field(
fields => [
      $ds->field( "keywords" ),
    ],
    value => "coronavirus",
);

Hello All,

I hope everyone is well in body and mind.

I need some help with the EPrints search function. I have been asked to add a box to the repository homepage that lists the latest coronavirus-related deposits.

I'm hoping to search via keywords for "coronavirus" and "covid-19". I also want to search for either of these terms in titles. To do this I'm currently butchering a copy of cgi/latest_tool.

I can get the keywords part to work using:

$c->{latest_rona_modes} = {
default => { citation => "noauth" },
fplatest => {
citation => "popular", max => 5,
#citation => "result", max => 3,
filters => [
#{ meta_fields => [ "full_text_status","full_text_status" ], value => ("none"||"public") }
{ meta_fields => [ "keywords" ], value => "covid-19"}

This also works with "title" as you would expect.

What I really want is to do a search where the keywords can be "covid-19" OR "coronavirus" as well as including some allowance for adding an:

 "OR title LIKE '%covid-19%' OR title LIKE 'coronavirus' in MYSQL-speak.

Am I able to do this using the EPrints::Search plugin? I've tried reading the codumentation and experimenting with it, but I'm not getting very far.

If it's not possible I can think of a number of bodges for it, but decided it was best to attempt the proper way first.

Thanks,
James
