You should follow a step-by-step approach to generate the SPARQL query:
1. Determine possible entities and properties implied by the user question.
2. Use the functions to search for entities and properties in the knowledge graphs. Where applicable, constrain the searches with already identified entities and properties.
3. Gradually build up the SPARQL query using the identified entities and properties. Start with simple queries and add more complexity as needed. Use the execute function to get feedback on intermediate queries. You can go back and forth between knowledge graph searches and SPARQL query executions to refine the query.
4. Use the answer or cancel function to finalize your answer and stop the generation process.

Additional rules:
1. Explain your thought process before and after each step and function call.
2. Do not assume or make up any entities or properties without verifying them with the knowledge graphs and functions.
3. The SPARQL query should always return the actual identifiers / IRIs of the items in its result. It additionally may return labels or other human-readable information, but they are optional and should be put within optional clauses unless explicitly requested by the user.
4. Do not stop early if there are still obvious improvements to be made to the SPARQL query. For example, keep refining your SPARQL query if its result contains irrelevant items or is missing items you expected.
5. Do not perform additional computation (e.g. filtering, sorting, calculations) on the result of the SPARQL query to determine the answer. All computation should be done solely within SPARQL.
6. For questions with a "True" or "False" answer the SPARQL query should be an ASK query.
7. Do not use 'SERVICE wikibase:label { bd:serviceParam wikibase:language ...' in SPARQL queries. It is not SPARQL standard and unsupported by the used QLever SPARQL endpoints. Use rdfs:label or similar properties to get labels instead.

[User] when was the magazine in which hunter x hunter is published established?

[Assistant] To answer this question, we need to identify the magazine in which Hunter x Hunter is published and then find out when it was established. Let's start by searching for the magazine associated with Hunter x Hunter.

[Tool] Invalid SPARQL query: Variable ?search must occurr in the WHERE clause at least once

[Assistant] I made a mistake in the SPARQL query. The `?search` variable should be used to match the magazine. Let me correct that and try again.

[Tool]
No entity items found

No other items found

[Assistant]
It seems that the search did not return any results. Let's try a different approach. We can first find the magazine where Hunter x Hunter is published and then look for its establishment date.

First, let's find the magazine where Hunter x Hunter is published.

### Step 1: Find the magazine where Hunter x Hunter is published

We will use the property `P1433` (published in) to find the magazine.

[Tool] Got no rows and 1 columns

[Assistant]
It appears that the initial query did not return any results. Let's try another approach by searching for the magazine directly using the title "Hunter x Hunter" and then finding the publication information.

### Step 2: Search for the magazine directly

Let's search for the magazine where Hunter x Hunter is published.

[Tool]
No entity items found

No other items found

[Assistant]
It seems that the search for the magazine using "Shonen Jump" also did not yield any results. Let's try a different approach by directly searching for the magazine where Hunter x Hunter is published and then finding its establishment date.

### Step 3: Directly search for the magazine

Let's search for the magazine where Hunter x Hunter is published using a broader search term.

### Step 4: Find the establishment date of the magazine

Once we have the magazine, we can find its establishment date using the property `P571` (inception).

Let's start by searching for the magazine.

[Tool]
No entity items found

No other items found

[Assistant]
It seems that even searching for "Weekly Shonen Jump" did not yield any results. Let's try a different approach by directly searching for the magazine and then finding the publication information.

### Step 5: Search for the magazine directly

Let's search for "Weekly Shonen Jump" and see if we can find the magazine entity.

### Step 6: Find the establishment date of the magazine

Once we have the magazine, we can find its establishment date using the property `P571` (inception).

Let's start by searching for the magazine.

[Tool]
Top 10 entity alternatives:
1. Weekly Shonen Jump, also known as Weekly Shonen Jump Alpha, Weekly Shonen Jump (American magazine) (wd:Q3540557): American digital manga anthology

No other items found

[Assistant]
The search returned the entity for "Weekly Shonen Jump" (wd:Q3540557). Now, let's find the establishment date of this magazine using the property `P571` (inception).

### Step 7: Find the establishment date of the magazine

Let's execute a SPARQL query to find the establishment date of "Weekly Shonen Jump" (wd:Q3540557).

[Tool]
Got 1 row and 1 column:
| ?establishmentDate   |
| -------------------- |
| 2012-01-01T00:00:00Z |

[Assistant]
The establishment date of "Weekly Shonen Jump" (wd:Q3540557) is January 1, 2012.

However, it seems that this is the American digital manga anthology, not the original Japanese "Weekly Shonen Jump" where Hunter x Hunter is published. Let's try to find the original Japanese "Weekly Shonen Jump" and its establishment date.

### Step 8: Search for the original Japanese "Weekly Shonen Jump"

Let's search for the original Japanese "Weekly Shonen Jump" and then find its establishment date.

### Step 9: Find the establishment date of the original Japanese "Weekly Shonen Jump"

Let's start by searching for the original Japanese "Weekly Shonen Jump".

[Tool]
Top 10 entity alternatives:
1. Weekly Shōnen Jump, also known as Shōnen Jump, WSJ, Weekly Shounen Jump, Weekly Shonen Jump, Shounen Jump (wd:Q220015): Japanese manga magazine
2. Weekly Shonen Jump, also known as Weekly Shonen Jump Alpha, Weekly Shonen Jump (American magazine) (wd:Q3540557): American digital manga anthology

No other items found

[Assistant]
The search returned the entity for the original Japanese "Weekly Shonen Jump" (wd:Q220015). Now, let's find the establishment date of this magazine using the property `P571` (inception).

### Step 10: Find the establishment date of the original Japanese "Weekly Shonen Jump"

Let's execute a SPARQL query to find the establishment date of "Weekly Shonen Jump" (wd:Q220015).

[Tool]
Got 1 row and 1 column:
| ?establishmentDate   |
| -------------------- |
| 1968-01-01T00:00:00Z |

[Assistant]
The establishment date of the original Japanese "Weekly Shonen Jump" (wd:Q220015) is January 1, 1968.

Therefore, the magazine in which Hunter x Hunter is published was established on January 1, 1968.

Here is the final SPARQL query and answer:

```sparql
SELECT ?establishmentDate WHERE {
  wd:Q220015 wdt:P571 ?establishmentDate
}
```

Answer: The magazine in which Hunter x Hunter is published was established on January 1, 1968.
