Question

I want to implement a search function in my application based on these tables.

I have 5 fields on search page

1. Input box – Keywords or any word in the title
2. Author – Select Box (author_id will be passed to the function as value)
3. Category Name – Select Box (category_id will be passed to the function as value)
4. themonth – Select Box from 1 – 12
5. theyear – Select Box from 2000 – 2012

I want to create a search query from based upon these rules,

1. Results array will be sorted by insights.read_time, (how many times the article has been read)
2. Only want to get the article.article_id

Pre-mature working working example is here

I am running following query to get but it is not complete
https://leading-people.com/search

SELECT article.article_id FROM article WHERE
article.is_active = ‘1’ AND (content LIKE ‘%%’ OR title LIKE
‘%%’ OR tags LIKE ‘%%’) UNION ALL SELECT article.article_id
FROM keywords INNER JOIN article WHERE article.is_active = ‘1’
AND (article.article_id = keywords.article_id AND
keywords.keywordtext LIKE ‘%%’)

TABLE article
COLUMNS

• article_id (PRIMARY)
• is_active
• title
• themonth
• theyear

TABLE article_author

Comments: This table is just for reference author details is in another table. So these id(s) are just for reference.

COLUMNS

• article_author_id (PRIMARY)
• author_id
• article_id

TABLE article_categories

Comments: This table is just for reference categories details is in another table. So these id(s) are just for reference.

COLUMNS

• article_categories_id (PRIMARY)
• article_id
• categories_id

TABLE insights

Comments: This table is just for reference categories details is in another table. So these id(s) are just for reference.

COLUMNS

• insights_id (PRIMARY)
• article_id
• read_time

TABLE keyword

Comments: This table is just for reference categories details is in another table. So these id(s) are just for reference.

COLUMNS

• keyword_id (PRIMARY)
• article_id
• keywordtext

Hope! I’ve formatted it correctly so everyone can understand!

After struggling for 6,7 hours, I was amazed that it was so simple 🙁

Here is the solution that I came up with

SELECT article.article_id FROM article WHERE $cond (content LIKE ‘%$term%’ OR title LIKE ‘%$term%’ OR tags LIKE ‘%$term%’)
AND article.article_id IN (SELECT article_categories.article_id FROM article_categories WHERE categories_id LIKE ‘$cat’) AND article.article_id IN (SELECT article_author.article_id FROM article_author WHERE author_id LIKE ‘$author’)

UNION ALL SELECT article.article_id FROM keywords INNER JOIN
article WHERE $cond (article.article_id =
keywords.article_id AND keywords.keyword LIKE ‘%$term%’) AND
article.article_id IN (SELECT article_categories.article_id
FROM article_categories WHERE categories_id LIKE ‘$cat’) AND
article.article_id IN (SELECT article_author.article_id FROM
article_author WHERE author_id LIKE ‘$author’)
